Amazon.com: Customer reviews: Sunny Health & Fitness Magnetic Rowing Machine Rower with 8-Level Resistance, Extended Slide Rail & Digital LCD Display

Reviewed in the United States on February 4, 2024

I’m 54 and in good shape but wanted to work on my cardiovascular fitness. I have been wanting to purchase a rower for quite some time and almost bought the Aviron for (2400.00). I didn’t really want to spend that much money. So I took to Amazon and checked out several rowers. I came across this one at 18,000+ reviews for a really cheap price (compared to 2400). It’s a good, solid machine and my husband said it was really easy to put together. It’s not as a good as a high end machine and it’s a bit difficult to explain why. First - the foot pedals move so it’s difficult to get a good push off from the heels. It works well enough but it’s lacking in that area. The machine is quiet for the most part (seat moving makes a bit of noise). The resistance is easy to change and I can see the display just fine. My other issue is the pull…it just feels off especially if you are following a video and they want you to pull high or do bicep curls. It’s minor but enough to notice. Like I said it’s difficult to explain. I’m not doing any major rowing on it…a few times a week for 20 minutes. And if I stop using it I’m not out 2,000 bucks. I’m happy with the purchase.
EDIT: I keep having pain in my legs and butt and I don’t know why. I can’t adjust the seat or pedals.

Excellent Value

Despite what some others have said, I think this is an excellent value.

After hours of research I chose this machine over others even though it was more expensive then I had originally planned on spending. However, a sale coupled with a damaged-box discount gave me such a supreme bargain I couldn't resist.

And I'm really glad I purchased it.

Packaging was stellar. Nice, tight packaging with small wood blocks insured no shifting of the machine during transport. All tools and parts were included and instructions were excellent. I put it together in 25 minutes. The most trying parts were the pull pin and large black knob on the top of the main frame which must be carefully lined up to fit. Lifting the frame up enabled me to shift the frame pieces into better alignment and slide the black knob piece directly down at the perfect angle. Otherwise, it will resist screwing into the hole.

The parts were shrink-wrapped on cardboard and clearly labeled as to which step they were for. This was extremely helpful.

The machine works smoothly and very quietly. The seat glides nicely on the rail with no bumping or catching. The flywheel is very quiet and turns smoothly. I have not used the computer readout yet so can not rate it.

I am 5'1" tall with a 27.5 inseam. When my legs are fully extended there is 13.5" of unused rail behind the seat until the seat would contact the stop bumper. Taller people would have plenty of room on the rail.

I have seen comments about feet slipping out of the foot rests. Please note the foot rests have two adjustments. The straps come pre-installed in the 'upper' slots closer to the toes of the rests. This is great if your feet are longer. For shorter feet, simple unthread the foot straps from the current location and feed them through the other slots closer to the heel of the foot rest. (See my photos for clarification). This will fasten the straps over the foot for smaller feet and prevent slipping of the foot.

I am including a close-up of the parts that attach the main frame to the seat rail frame. I am doing this because if you don't have all of the pieces together the frame will shift and the seat will not glide smoothly. I watched another purchaser's video where they were complaining about the seat not gliding and being noisy. If you look at her video you will immediately notice she has one of the bolt holes empty, causing the entire frame to bow down at that crucial point. Follow all directions and the frame will be totally tight and secure.

Personally, I love the machine. This is wonderful and I anticipate it providing me with many hours of relaxing rowing.

Note: If you feel the machine is not giving you a good workout, check your technique. Poor technique is responsible for 95% of dissatisfaction with most exercise equipment, in my opinion. Do yourself a favour and watch several videos from different sites to learn proper technique. Even if you have used a rowing machine before, don't second guess yourself. Good technique is the only thing you can do to guarantee a great workout, increased strength and health and to protect yourself from injury.

Dark Horse Rowing has a series of videos that are very nice. Otherwise, check out college rowing instructional videos. The video that is part of the advertising for this machine shows extremely poor technique. Do not use it for reference.

Excellent value especially for beginners.

Reviewed in the United States on August 18, 2017

I've been using this rower for a couple of months now and I like it. I'm a senior looking to get some cardio and muscular improvement without killing myself in the process. Running in the summer time Florida heat was out of the question so I tried this rowing machine.

The machine itself seems well built and functions smoothly when I use it. I've had no problems with it so far. It's very quiet; the only real noise is the seat sliding back and forth.

Assembly was straight forward. I suggest moving the wheel section of the machine to its final location before starting assembly. This will require an assistant since it's somewhat cumbersome. If you're a young muscular guy you can probably handle it yourself. You can bring the remaining parts to the new location in batches as you assemble the machine. Or, tip the delivery guy to carry it to its destination on his dolly. Mine came by UPS.

The machine itself has a few deficiencies. The first is the control panel. It's really basic and hard to read unless you have good light. The display itself is not self illuminated. There is no stroke rate indication which I think is very important since that's what indicates your level of effort. I set the panel to the stroke counter and use a separate stop watch on my phone to keep track of the time. I could probably use the timer on the control panel but frankly it's so cumbersome to cycle through the functions and hard to read (old eyes) that it's easier to use a separate device.

When battery replacement time comes it's going to be really hard to get the panel out of its hole. The manual isn't too specific but there is a tab along the bottom of the bezel which you lift up to unlatch the panel and pull it out of the recess. The problem is that there is nowhere to grip the frame of the panel to pull it forward so a tool, like a screw driver is needed to get it started moving forward so you have something to grip.

The second deficiency is the folding mechanism. The 2 major parts pivot on a long bolt and are locked in the functional position by a threaded hand knob for rigidity. This hand knob is unscrewed to allow the long section to pivot up for storage. In the up position you insert a pin which prevents the long section from falling by accident. I found the alignment of the holes for this pin don't allow for easy insertion of the pin. In my case I really don't need to fold the machine but you might feel differently.

I don't feel like these deficiencies are that significant on a machine at this price level. All in all these problems are minor and the basic functioning of the machine is sturdy, smooth, quiet and so far reliable. For the price I think this is a very good buy especially when you consider the price included shipping which can't be trivial. My aim was to get a reasonably good but inexpensive machine to try rowing and if I felt like I had a future with a rower I could move up later after I learned enough to make an informed purchase. So far so good.

I use it on a fairly low resistance setting (3 of 8) which, for now seems like a good level. I've had no expert advice about how to exercise so my information is from on line reading. I set my exercise time by the number of strokes. I started with 50 strokes, admittedly not much but enough to see what was going to hurt the next day - my shoulders, which still limit how fast I increase my exercise time. Every few days I add some strokes until now I'm up to 250 which takes about 10+ minutes. Still not enough but I've observed a few things as I proceeded. First, heart rate doesn't increase the longer you exercise. After the first 50 strokes or so your heart has adjusted to the new level of exertion and will maintain that rate as long as you maintain the stroke rate and resistance setting. This rate (about 23 spm) is comfortable for me and my heart rate is into the "vigorous exercise" range for my age recommended by the American Heart Assoc. So my goal now it to increase the time until I get to their recommended duration.

There's a little bit of technique to rowing that you can get information about from several sources on line. But the one thing that helped me a lot wasn't mentioned anywhere and that is to synchronize your breathing with the stroke. I find it much easier to breath in on the stroke and breath out on the recovery. My comfortable stroke rate is about 23 spm but when starting your breathing rate is less than that so it takes a conscious effort to sync the breath and stroke. As I start to breath harder it's easier to sync the two after about 50 strokes and then I get into a rhythm that works for me at this level of effort. If you're out of sync and try to breath in on the recovery your knees will compress your diaphragm and prevent you from getting a good breath.

If you're a senior like me who has moved to a more sedentary retirement lifestyle take it easy at first and move to more strenuous levels slowly. You won't find out what you're stressing until the next morning. I still find it interesting because I'm keeping all the numbers in a spreadsheet but I'll soon need some kind of entertainment while rowing to keep boredom at bay.

6/14/19
A few months ago the foot straps gave out. The metal oblong rings kept slipping to one side and that would effectively lengthen the strap so it didn't hold my foot firmly any more. This problem came on slowly but finally became a real nuisance. I bought some straps (https://www.amazon.com/gp/product/B01ATL97U8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) from Amazon to replace the originals and they worked fine.

In all other respects the machine still works fine with no problems, just clean the seat track occasionally. I'm up to 375 strokes at tension 4 and continue to work on my technique. I noticed the price of the machine is even lower than when I bought mine so I consider it an even better bargain at this price.

5/25/20
The new foot straps mentioned above allowed me to pull the straps tighter than the original Velcro straps and as a result I have broken the plastic of both the foot pads on the inside where the strap comes up from beneath.

I repaired it by hot gluing a piece of strap metal to the bottom of the foot pad that spans the break. This seems to work fine so far. The metal part takes the load that caused the plastic to break. No big deal.

I don't think this was a defect in the product and I'm not changing my opinion that this is a good value for a beginner machine. My mistake was using much more tension on the foot straps after I replaced the originals with a different type of strap that allowed for pulling them much tighter. Obviously I didn't need to pull them as tight as I did so this problem is on me.

There have been no other problems with the machine other than replacing the battery in the control panel and cleaning the seat track occasionally.

I would definitely buy it again! SUNNY Health & Fitness Magnetic Rowing Machine

Reviewed in the United States on December 8, 2017

Style: ClassicVerified Purchase

WHY I CHOSE IT:
I'm a 54 yo 5'6" woman with a BMI of 27.4: I'm fairly muscular but need to lose a minimum of 16 pounds to reach a healthy BMI of 24.9..Ideally, I'd like to lose 30+ pounds. I am an RN and am on my feet most of the day. I chose the rowing machine because: (1) rowing is said to use a greater number of muscle groups and burn more calories than ellipticals or treadmills, (2) rowing is very low impact, (3) this machine has a pretty small foot print and stores relatively easily, (4) the price was right.

WHAT TO EXPECT ON DELIVERY:
ARRIVAL was 2 days after ordering. The total weight in the box is 67.2 pounds: Out of the box, 57.3 pounds. It arrived without any damage to the packaging or the unit. The packing was excellent. There are 7 parts: (1) The main front mechanical drum(main frame) is all in one with the pullbar/strap and timer/counter already in place, (2) slide rail, (3) seat, (4&5) front and back stablizers, (6&7) right and left foot rests....AND 2 packages of bolts/washers/knobs/and tools with an instruction booklet.
ASSEMBLY was pretty straight forward. The connectors and tools were all present and all fit in their assigned holes. The instruction manual is step by step and easy to understand. The unit is a bit bulky and my 14 y/o daughter's assistance was a blessing. It took about an hour to unpackage, read, and assemble, but a second one would take about 20 minutes door to completion.
There are wheels on the front end so it can be tipped up and moved from room to room; however we assembled the slide rail to the main frame where it was to be used. I didn't want to scratch my floors. I'm using a rug underneath but plan to get the recommended mat to keep it from scooting (slightly) during use.

MAIDEN VOYAGE:
I watched a YouTube video to learn how to position myself during use. (BTW: There are actually workout videos for rowing on YouTube)
I like the seat of this unit. It is textured and has an angled back edge. I think without the two I might slide off the back.
Wear shoes or you will get blisters on your heels, and you will have more stability with them on. Any other clothing is up to you; just be comfortable.
The timer includes time, strokes, and calories burned. I'm not sure about the accuracy of the calorie counter. Everything I've seen online is about double what this unit indicates but my goal is heart rate and a balanced muscle involvement. So that doesn't matter to me.

COMFORT and EASE of USE:
The machine is very comfortable. I have to adjust my stance at times to avoid knee discomfort but overall I am satisfied with ease of use and comfort.

LEVEL of WORKOUT:
I have used this machine twice for 35 minutes each time using the level 3 out of 8 intensity setting, I have been able to achieve a moderate to vigorous cardiovascular target heart rate. I can feel very mild stiffness the majority of my major muscle groups (legs, glutes, abs, lats and back, deltoids, biceps, and triceps). I'm not sore by any means but it is nice to feel something. I imagine that in time my coordination will improve, I will need to increase the intensity and speed of motion very soon, and I will get a better and more intense CV and muscular workout.

RECOMMENDATION:
I think this is a safe and simple and inexpensive way to get a decent CV workout and to improve overall strength and flexibility. Stretching before and after is recommended. It isn't going to get me ready for competition but in just a couple of days I feel more balanced, coordinated, and energized. I recommend this unit for beginners and anyone who wants to keep moving, burn calories, and stay flexible. I'll let you know how it works out over time.

RATING:
I gave a 4 star rating. Minus one star because avid crew team members could not maintain competition performance on this machine. However, for the rest of the world, it is easy to order, easy to pay for, easy to assemble and store, easy to use, and provides decent CV workout for the average person.

Best Cardio Machine on the Market, $ for $

Reviewed in the United States on September 29, 2020

Style: ClassicVerified Purchase

For context: I'm a fit, 6ft 175lb 36 year old and ex collegiate athlete. I moved to a place where running in the winter is something only masochists engage in, and wanted something to replace my daily 5K. When I purchased this a couple of years ago, I thought it'd either lead to me turning to something other than rowing or upgrading to a more expensive rower if I enjoyed it as my running alternative. I still have this, it gets used at least 5 days a week for 6 months of the year and maybe 3 days a week the rest of the year in 20-30 minute high intensity intervals. Below are the pros and cons.

PROS:
- I can't believe this machine costs what it costs, for the $ I really don't think you're going to get a more effective or durable cardio machine (caveat - if you're a heavier human, this might not hold up as well as it has for myself. My weight fluctuates between 175lb and 185lb...I'd say that if you're 200lbs or less, this machine should handle your weight without breaking a sweat. I know that it has a listed weight limit, whatever it is I'd go by that when considering this machine);
- LOW maintenance - I haven't had to do anything to maintain this machine and I've had it for years.
- Easy to assemble (it does take some time, but not as much as you'd think);
- Effective workout - I've used high-end rowers in fitness clubs since getting this, and while this isn't EXACTLY comparable to those, it's not far off and the price difference is enormous...just row faster! (it mostly lacks higher resistance levels, but it's highest resistance should be more than adequate for most people);
- Relatively small footprint (check the dimensions - I have it basically running along the shorter wall of a small bedroom and it really takes up hardly any space);
- Minimum noise - none of these are whisper quiet, but this is quieter than most...it has developed some additional noise over the years, but it is still relatively quiet considering it's an erg.

CONS
- Noise (but that's any of these machines);
- Limited range of motion...I think I'd ideally like a couple of extra inches, but if you're 6ft or shorter this should still pretty much work fine for you to get in a full stroke;
- Limited display - this is probably its most significant shortcoming...I wish it displayed strokes per minute (easy enough to determine by doing a little math, but who likes to do math while they're trying to work up a sweat?);
- Resistance (as mentioned previously) - for most, this will provide more than enough resistance...and if it doesn't increasing the pace is always an option.

The slight lack of resistance, slightly limited range of motion for anyone in the 6ft+ range, and rudimentary display/tracking options are the things that keep this from being comparable to much higher end rowing machines...but if all you're looking to do is work up a sweat via a low impact workout, I really don't think you can beat this $ for $. I've thought of buying a slightly higher-end rower since getting this one 3 years ago, but can't justify the additional cost.

Excellent Low-Priced Rowing Machine!

Reviewed in the United States on August 9, 2020

Like many others I customarily used a Concept II rowing machine, the gold standard, several times a week at my health club. However, my fear of visiting the club since March because of COVID19 with the expectation that the situation will last at least until the end of 2020, led me to purchase a rowing machine for my home. I thought about purchasing a Concept II but it is four times as much money and as of early August 2020 has a ten week waiting list. The Sunny SF-RW5515 was rated "best budget rower" on the Internet site I visited so I ordered one from Amazon. I have not been disappointed. During these first few days of use I have been very pleased with the Sunny, and would highly recommend it to others with similar needs. I wish I had purchased it months ago. I don't know whether it would stand up well with heavy use at a health club or boathouse, but for home use it should be fine.

The Sunny is a solid, well-designed, well-built device. It uses magnetic rather than air resistance, which has the advantage of being almost silent during use. The resistance is adjustable and in my view the range should be more than adequate for anyone except perhaps a national team heavyweight rower. The seat moves smoothly up and down the rail; the mechanism uses a fiberglass belt rather than a bicycle chain. It doesn't appear that any maintenance other than occasional cleaning, and lubricating the seat, will be necessary. The computer measures number of strokes per workout, elapsed time, total strokes and calories burned. (The latter is probably not very reliable.) A scan function that automatically changes data functions every three or four seconds is also provided. The foot rests with Velcro straps should work well regardless of the user's foot size. The rower can be moved from one room to another using wheels built in to the forward cross bar, and the main strut folds to vertical for storage, with the removal of two bolts (no tools needed).

Assembly was straightforward despite the large number of sub-assemblies and fasteners. I paid attention to the suggestion in the excellent manual to read through the entire manual first, then carefully followed the instructions. Each stage of assembly was sequentially labeled with detailed diagrams, with the parts for each step packaged separately. The necessary tools were provided. All of the parts fit together as intended. It took me almost as long to unpack the rower, carefully removing cardboard, plastic sheathing and styrofoam as it did to complete the assembly. It's basically a one person job. (My Amazon delivery guy carried the 70 lb. box up several flights--kudos, Amazon!)

I haven't yet encountered any disadvantages other than the monitor. My only minor quibble as a rower is that the computer does not measure time for 500 meter or strokes per minute, the standards used by Concept II and boats on the water but the computer is very helpful for gauging your workout in other respects. Sunny makes several other models, including one at a slightly higher price that permits you to use the rower vertically as an arm and shoulder exercise device, a feature that some prospective purchases may wish to consider.

Update: after frequent use over several weeks I find that the computer/monitor is annoyingly limited. If you are rower you might want to buy the model 5622 at a slightly higher price instead. It appears to provide a distance function in addition to time, stroke count for the workout and calories (along with total strokes up to 9999, which is mostly useless if there is more than one user in your household). One option for iPhone or iPad owners is a free program called "Metrownome." You can set it for whatever number of strokes per minute you prefer, and the proper ratio between power stroke and recovery (useful if you tend to rush the slide as I sometimes do). I was tempted to lower my rating from five stars to four because of the deficiencies of the monitor, but overall this is a very well made and functional rowing machine for the price.

Review after a 3-days of use

Reviewed in the United States on March 19, 2024

Style: SmartVerified Purchase

The rowing machine was easy to put together. I did it while watching TV. Simple nuts and bolts. The instructions were clear and the hardware needed were aligned to the step involved in putting it together. For example, Step 1 and there was a set of hardware for that and then Set 2 and there was a separate pouch of hardware for that and so on. 6-steps, I think and the rowing machine was ready.

It doesn't have BT but that is not an issue, for me.

The length is good for a comparatively small and foldable footprint. The levels of resistance were good for me (I am 52M). The display is fairly rudimentary but that's cool too. I reset after every workout and then start again.

The only area, thus far, that I have found annoying (as have others that I watch TV with) is that the seat is noisy when sliding back and forth. So, the flywheels themselves are quiet which is great (no chain ratting there) but the seat makes up for that rattling. So, the machine is not a quiet machine, just in case someone was looking to buy a "quiet" machine.

I will update this again in some time. My previous experience with a Sunny stepper was a poor one and am really hoping that this will be better.

Sunny Health & Fitness Magnetic Rowing Machine SF-RW522016

I have only had this for a day, but so far it seems very nice. It was packaged very well and if you take your time and follow the instructions it's very easy to set up.

I've been out of shape for a few years and really need to get back into fitness. I chose rowing because it works a larger percentage of your body and it's low impact.

I had a limited budget and did a lot of research before finally settling on a magnetic rower and this specific model.

I was a little concerned with the tension being too light, as stated on a lot of reviews I read. I can see where that may be the case for some who may be top level athletes or using the rower incorrectly. Again, it's only my first day so I will update another time when I have more experience with it.

On initial review I only gave it 4 stars because like most of the lower end models the foot pedals are placed too close to where the strap enters the machine so you only get 75% of the reach when you're in the full forward position (the catch position). I knew this going in, but none the less decided something was better than the nothing I was currently doing. The other issue is the pivoting foot pedals. I can see where it might be helpful for some who have foot or ankle mobility issues, but for the most part, all the research I've done suggests that a non pivoting foot plate is the best to maximize your workout. Again, I knew this going into buying this model.

Bottom line...if you do a lot of research you will find that almost no one will recommend a budget rower. They will most likely recommend the Concept 2 (which is the gold standard of rowers) and tell you to wait and save your money for it. It is a great machine and this would be excellent advice for those who have that kind of money or are willing to wait until they save up for it. In my case, that would be a very long time and I wanted to get started now.

On first review, this machine seems to be a very well put together and effective rower for its budget price point of around $300. I am looking forward to seeing how this works for me and will update my review when I have more experience with it.

Rower With Promise

Reviewed in the United States on February 11, 2021

Style: ClassicVerified Purchase

I looked at a lot of products, even explored the wait listed rowers especially Concept2 at $950.
Their factory tells me to expect a late March order window, and that estimate already retreated once.
Some people on the local Craigslist are offering those machines "NIB" for $1150-1200, cash.
Anyway, I was surprised by the number of "rower" machines are on the market.
All price ranges.
But looking more closely it seems that many of the search hits, and price point options, are basically knock-offs.
I never rowed before but some research effort tells me that rowing is good for various muscle groups, low impact, and engages cardio pretty well. Water, air, magnetic and hydraulic. OK.

This product looks good, and I need to shed some quarantine pounds.

The box it came in was pretty big, a two person lift for most.
50x25x10 inches and around 70#, awkward, no handles. I missed the UPS delivery, so I don't know if one person dropped it off. I managed this one end over end up a flight of stairs by myself. I'm 6'2". Did not have to lift the entire weight once.

The box has instructions on how to remove the machine.
You open the top, indicated by arrows. Move all the flaps outward, invert the box to drop the contents out when you lift away the cardboard shell.
Inverting the box was a little awkward I think.
But it worked as described for me.
The contents are tightly corralled with Styrofoam sections, all wrapped tight with plastic, so it drops out by weight pretty smoothly in one big piece.

Assembly I gave 5 stars for "ease." That is all relative to me.
See pics, the assembly is well-organized, so "easy."
If you are not used to bolts and wrenches you might need help.
But the instructions and hardware laid out in shrink wrap are well-organized.
Cutting the pieces out of the plastic is easier than cutting those hard clamshell packs so common in retail.
These parts are shrink wrapped with something more soft, which requires much less pressure to slice with a pocket knife.

The assembly instructions are OK, the pics are somewhat tiny, but the text is clear and thoughtfully bold in reference to part numbers.

I took my time, might have took 1 hour. I applied blue thread locker to bolt threads, except the hinge bolt at the front of the seat bar, since it occurred to me that I might want to remove that bolt to break the machine into 2 parts.

The front foot, one side gave me a little trouble, the bolt wouldn't thread easily into the receiving capture nut welded inside the foot piece. Had to test repeatedly to avoid cross-threading that bolt into the nut. Finally, I concluded that the nut had some of the paint from the frame inside the thread area, and I could try to push with increased torque to drive it through the paint dribble that shouldn't be there.
In hindsight, I should have reamed that nut out with a small wire brush/tool to remove the excess paint applied at the factory.

The hardware packs include tools which I used for assembly. Nothing extra was used, except Loctite threadlocker.

In my opinion, some people might not be able apply enough torque on the fasteners with the provided tools.
The "spanner" wrench can hurt your hand maybe before you have pushed hard enough to properly secure the footpad bolts. I recommend using a piece of cloth in your hand as extra cushion when assembling/pushing on those bolts. There is a point, when pushing with a thin metal wrench, and judging how hard can you push, when the metal might just fail, either the bolt head or the wrench itself.
If the bolts are not properly tight, when using the machine things will start to rattle and move after awhile, or sooner.
I am familiar with bolts and such, and feel that I was able to wrench everything just about right.
However, I think that the tools provided might hurt some users' hands before things are tight enough.
The Phillips tool, used on the rear stop for the seat, has just enough "handle" purchase for those 2 screws if you have a strong hand.

If you are inexperienced with tools, be aware that you might not get everything as tight as it should be, when using the tools provided.

I looked inside the front case when I removed the electronic piece to install batteries. Everything looked good in there. The instructions refer to attaching wires but it seems that some units are now shipping with the wiring already complete. There were no connections necessary in my case.
There was a velcro wrap around the battery holder, be careful fishing that back through if it slips apart from things, as mine did. It might snag on the way back under the battery holder. Be especially careful around the electronic part, it is a circuit board so don't want to press too hard on any particular component or wire.

Once it was assembled, I tested the action. Seems solid. Will update later as new info arises.

UPDATE_2/13/2021:
1- The seat wobbled just a little while gliding along the rail, but this was easily corrected. The roller that rides beneath the rail has an adjustment bolt on each side and one side needed just a wee bit of tightening.
2- If you need to fold the machine for storage (I do) it can be a little tricky. There are 2 parts that must be installed for use, and removed to fold. A straight pin that passes right through the rail from one side to the other, and a knob-handled bolt that screws down from the top. You have to lift the rail with one hand to get the pin holes to line up, and then pass the pin through. Sometimes it is hard to get the pin through the far side. The bolt then needs to be screwed in, and you need to be careful and avoid cross-threading. Lift up on the rail with one hand to get things to line up properly. I added some pics.

2/17/2021
When the rail is folded up, there is no lock or stop to keep it in place. And it seems easy to send it falling towards the floor. So I tied a length of paracord to the front foot, and made a loop on the other end that is just the right length to reach the rear foot when it is in upright position. I have not had the rail fall to the floor but it is quite heavy and would at least make a loud noise if not hurt somebody etc.
4/17/2021
Took me long enough, but I finally noticed that the locking pin serves to hold the frame in the upright (folded) position without need for my cord solution. After you move the frame rail into the upright position, just slide the pin through the holes behind it works as designed.

Reviewed in the United States on April 7, 2024

Style: ClassicVerified Purchase

I HIGHLY RECOMMEND SUNNY ROWING 5 STARS. Works like a charm. I bought this rowing machine to spend more time with my dogs at home so I don't need to go to the gym anymore. Because my dogs can't stand when I leave the house. I can do my rowing at home now. IT'S A TOTAL BODY WORKOUT. The rowing machine is really all I need as a woman to get my abs for summer swim season. I highly recommend this rowing machine because it's packed very well, easy instructions, and I'm very happy with my purchase. For anyone wondering about rowing, if I do the rowing for 60min-120min a day along with eating a lot of eggs and egg whites, I'm going to get in strong, lean, ab shape incredibly fast for summer. I don't get the ab results from other machines at the gym as I do from the rowing machine. The rowing machine is the only machine I need to get abs. It gets me in shape very fast over any other machine. I HIGHLY RECOMMEND SUNNY ROWING to anyone thinking of buying a rowing machine for at-home use for ab work and total body work because this is the TOTAL BODY WORKOUT machine, it's very easy to assemble, and it comes with batteries for the digital monitor. Thanks! Tatiana
