  • Quality bench, easy to use, very sturdy
Style: Bowflex 5.1s Bench
Purchased this bench as part of the beginnings of putting together a home gym. We're short on space, so it was important that it had a small footprint. Assembly was relatively straightforward, and if you can put together a small Lego set then this should be a breeze for you. Total assembly took about 30 minutes, and you'll want a knife or a pair of scissors to work through the packaging. Allen keys to assemble everything are included. During assembly, the "heavy-duty-ness" of the frame was apparent, and I wouldn't hesitate to load this bench up with the recommended max weight (person plus weights) of 600 pounds. Once assembled and flat, it does take up some real estate; in the stowed position, that's cut down to about 1/3rd. In the fully declined position with seat lifted, decline sit-ups feel just right with the ankle bar. The flat position is rock-solid when doing bench presses, and it's very nice to have several options for incline. The mechanism for raising/lowering the bench is a spring loaded "pull pin" type which allows the upright support arm to glide easily up and down the floor leg - no grinding or scraping sensations. Once your desired position is selected, you can allow the pin to pop in place which fully secures the back rest. Optionally, you can twist the same handle to lock the support arm and leg together to eliminate any play between them. The seat has two position options, flat of course, and then raised. In the raised position, it's high enough to fully prevent sliding down the seat when doing incline work but not so high as to be distracting. With the seat raised, it's also set at the same angle as the backrest when fully lowered, providing for a great base for decline work or for decline crunches/sit-ups. The seat mechanism is simple. Lift the seat up to lock it into the up position. Lift a small red lever to allow the seat to drop back down to the flat position. The rounded edge of the seat has plenty of flex to it, almost like I'm sitting down in my favorite recliner at first. I worry that this flex may lead to long term wear and tear issues, but without knowing the internal design of the cushion (no, I'm not tearing it apart) I have no evidence to suggest that my worries are true. The ankle holders are foam, not super soft, and they seem like they'll hold up for a good while - time will tell on both items. The ankle holder folds up for storage, but the mechanism which allows it to fold up also allows for some free play. You can get it to rattle quite a bit and make some noise if you grab it and shake it, though good security of the mechanism is apparent, and I expect it to be very reliable. The feet of the bench are adjustable, so if you don't have a perfectly flat floor, it will allow you to compensate. Some have indicated that the gap between the back rest and the seat is very wide. There is truth to that; the gap is 4" when the bench is fully flat and 2" at a 45 degree incline and raised seat. At a 90 degree incline, the back meets the seat. It would have been possible for Bowflex to eliminate this gap, but it would have required a much more complex mechanism resulting in either a higher cost or a lower quality product. To be honest, I find that my butt rests perfectly in the gap on a flat bench when my ankles are under the ankle supports which allows the back rest to provide support to the arch of my back, sort of like how a good car seat provides just that little bit of much needed support. Because the seat is roomy though, there is some space to move around a little bit, perhaps to locate the gap directly under the arch of my back, but there was no way that I could completely eliminate the feeling of the gap. The best that I could actually come to getting a "gapless" sensation was to actually lie on the bench backwards with my head on the seat and spanning the gap with my neck, though even that wasn't perfect. If you require a bench with minimal gap, definitely look elsewhere. Beyond that, the quality of the material looks solid, and I'm not worried that I'll damage the upholstery. It also looks very sharp. Oh, when it's on the casters, it doesn't *quite* fit through a standard 30" doorway unless the door opens a full 180 degrees. The total width of those legs is probably 28 1/4" wide. If you can turn it and pick it up though, not a problem. ... show more

  • Stows upright but could use a lot of improvement
Style: Bowflex 5.1s Bench
Like other bowflex products this is packaged very nicely. I don't know how long the product has been sitting in a warehouse but there's some fit and finish issues, mainly the inside of the adjustable frame shows a lot of oxidation (outside is painted but not the inside I reckon) which was highly visible around the frame in the form of bronze dust and in the bag it came with. I wiped down the frame before assembling the product with a rag and it turned a nice shade of brown. Not the end of the world but still. On the bright side, this is an easy bench to assemble with the exception of the end caps for the feet pads. Whereas I had to use online instructions for the 552/1080 stand, the bench is very straightforward. For the leg pad caps, a rubber mallet will help, but as I didn't have one I tapped them into the rod with a ball-peen hammer and harder bits of cardboard from the packaging so I wouldn't break the plastic caps. I simply couldn't press them in by hand and I had a second person helping me push from the other side, putting our full bodyweight into it. The end caps are not a great design, and the rod is slightly too long so there's some play with the leg pads. What would really make this bench better is more adjustments. Namely an 80 degree, 10 degree, and a -10 degree adjustment for upright presses and flyaways, respectively. Sometimes I just need a slight incline or decline. The adjustments are made by simply unlocking an adjustment peg and moving the frame into holes on one side of the frame. You may want to go down a model like to the 4.1s and do what I've seen other folks do — use a wood block to add extra adjustment positions for a less invasive hack. This bench does store upright and doesn't take up a whole lot of space and is light enough to move around. However, I'm not a fan of the wheels. I wish they were bigger and not quite as underneath the frame so you could roll it easier. Lastly, as others have mentioned, there is a considerable gap between the butt rest and the back rest. If you sit farther back on the butt rest when you decline, I do get a little creak out of the seat, so I end up scooching forward a bit. What I do like: padding and quality of the seat is very nice. Overall quality and stability is nice. I'm going to have this for a while and get a lot of use out of it even though I wish it offered a little more. I purchased this bench because the legs were wider than what I was seeing from the Asian brands and I didn't want a super heavy bench in my second floor spare room. From what I can tell, this is a good buy compared to similar brands because of how wide and stable the legs are. Depending on your height, this can be good or bad since the wide legs near the seat of the bench might be in the way of your feet. Look for a more traditional bench for non-Bowflex heavy barbell stuff, if you need more adjustability, need a narrow leg at the seat of the bench, or if you intend on working out in a garage or basement where you can have sturdier equipment. ... show more

  • Great bench
Style: Bowflex 5.1s Bench
I've been using this for about three months now and i really like it, it's solid, good thick seat/back and best of all, it's stow-able. I really like that about it and it's easy to move around with the two small wheels in the lower front legs. Con: It has a wide gap between the seat and back when it's folded flat for even in an incline/decline position, depending where the pin is at. Anyway, this is the only issue i see with this, i have to place a towel that fits snug in between back of the seat that bottom of the back rest, sucks. Overall great bench, solid and made welll. I'm sure it'll last a long time. ... show more

  • Great investment
Style: Bowflex 5.1s Bench
Pretty easy to assemble except final leg extension part. Directions weren’t detailed enough but figured it out by unassembling then reassembling but it’s only two screws. Overall though step by step directions were thorough enough. Final product is very sturdy and impressive quality. Has multiple bench positions and takes very little space when stored standing. Very cool feature. Definitely worth the investment for home gyms. ... show more

  • Nice bench
Style: Bowflex 5.1s Bench
The bench is very nice. The quality is good and it is comfortable. The only reason I gave it 4 stars is because if the unadjustable leg rests in the front of the bench. I who’s they were either adjustable or not there at all.

  • Feels like a thrown
Style: Bowflex 5.1s Bench
The seat on this thing is massive! The plywood under the butt pad flexes if you sit off center. Other than that, I’ve really enjoyed using this adjustable bench. There are more angles available on this bench than some of the other options I looked at before purchase. Glad I went this route, cause I’ve used every angle except decline already. Side note, but probably not advised, the bench will stand up and stow away even without the leg attachment installed. - - part of the reason I haven’t tried decline yet. ... show more
