Nitrofit Limber Pro Adjustable Seat Stretch Machine for Lumbar Stretching, Lower Back Pain, Leg Stretch, Rehab, Flexibility, Injury Prevention, Calves

NitroFit Limber Pro Stretch Machine is hands-down one of the smartest fitness investments I’ve made for my home gym. From the first session, it proved it’s more than just a “stretching gadget” — it’s a legit mobility tool. The sliding adjustable seat lets me dial in stretch depth with precision, which means my 6’2 frame actually fits the machine comfortably without awkward repositioning. That feature alone puts it ahead of most stretchers in this price range. The removable calf angle board is a sleeper-hit add-on. I didn’t realize how much tighter my lower chain was until I started using it regularly — and now my calves, Achilles, and hamstrings feel noticeably looser and more responsive, especially after workouts or long hours sitting. Build quality is impressive: solid steel frame, no wobble, stable base, and the front wheels make it easy to move when I need space. Assembly was simple and intuitive — 30 minutes, zero frustration. Results? That’s where this thing shines. After consistent use, my hamstring flexibility, hip mobility, and lower back tension have all improved. The stretch feels controlled, deep, and safe — like having a personal stretch therapist at home. If I had to nitpick: the padding could be slightly thicker, but honestly, for the price and the performance, it’s a non-issue. The stretch quality is what matters — and this machine delivers. Whether you’re an athlete, mobility-focused lifter, or someone wanting real recovery and flexibility gains, the NitroFit Limber Pro is a game-changer. It punches well above its price class and feels like commercial gym equipment without the commercial price tag. Highly recommended. 5/5 stars. — Dean Davis

I used a machine similar to this at the gym and loved it. After researching several machines offered on Amazon, I decided on this one. It is very sturdy and easy to use. You are in complete control, and can ease into each stretch to the point that you feel comfortable. There is the tiniest wobble when sitting on the seat, but I think it’s due to how the parts fit together on the adjustable base to allow the seat to move forward and backwards. It is very sturdy! I have had lower back and hip pain for a while now and this machine helps tremendously. The full routine of stretches, provided on the illustration panel, only take a few minutes and make a world of difference. I sleep so much better now without tossing and turning from aching all night. I bought this on sale, but it is worth every penny sale or no sale. My only note is that we don’t need the ability to adjust the base. Unless you are really tall, I doubt it would be an issue. The one at the club was smaller than this one and numerous people of all sizes were able to use it affectively. We keep it behind a chair in the living room, and it is barely visible (see picture). It makes it very easy to use in passing throughout the day and while watching TV in the evening. I had a question after I received it and I easily got in contact with the seller. They responded immediately and resolved my issue.

Very sturdy well built for home gym use. I used a Precor machine at the gym and wanted the same experience without spending $1,000. This unit does the job. Plus has a calf stretching platform that the precor does not have. The only reason for not giving a 5 star review is during assembly i had an issue with alignment on one of the components. The stabilizer nut was welded on not perpendicular to threaded rod making it very difficult to assemble. I was able to make it work by drilling the clearance hole larger. I would recommend buying this machine. Well worth the money.

Fantastic machine! I’ve suffered with back pain for years. I never knew until recently that this type of stretching equipment existed. It is a God send for anyone with back pain and poor flexibility. I have read all the reviews and watched some side by side videos on YouTube. This unit, the Nitrofit, is the best option in my opinion. I cannot see the more expensive units doing the job any better. In one online video there was a three way comparison, it showed that the Nitrofit is more stable than the most expensive unit of the three and had a better handle bar mount design than the other model. The only negative to this unit in any review I had read was the lack of extra padding on the front edge of the knee pad. The area where your knees rest has plenty of padding but when you are doing some of the leg stretches and the bottom of your leg is on the leading edge of the knee pad it can get a little painful. In my case I couldn’t tell if the pain was the lack of extra padding or if it was my poor flexibility…probably both! But I have solved the only negative to this machine and it is an easy and inexpensive fix. I added a replacement foam roller for another piece of equipment. All I did was slice it down the center on one side and it fit right over the edge of the knee pad. I ordered a 16 inch and it was the perfect length. I did notice that the foam roller would stay on during other exercises but it moved slightly. I trimmed a little more foam off the inside and used 2-inch-wide X 15 inch of Velcro to hold the roller in place. Since the Velcro is on the bottom of the knee pad you can take the roller off if you find it a distraction doing other exercises but I find it feels fine keeping it in place for all the exercises. It also gives you a little extra ‘lift’ and comfort when doing the Quadriceps. Check out the photos, here is a link to the same type of foam roller I used, these are sold in pairs so if you screw one up you will have a spare. https://smile.amazon.com/gp/product/B002URFCYU?pf_rd_p=faa1d3e1-fadf-4279-ac2d-3096206e4690&pf_rd_r=9RDHJJ760XQWEAMA5WJT With the calf stretch ramp, the overall stability, the quality, the exercise display, and with the one little modification the Nitrofit is the perfect stretching machine. My back feels better after a week with the Nitrofit than it has in years.

Great stretcher, thats half the cost of a precor. Its even better than a precor. Assembly is easy if you follow the video, which is very detailed and provides very clear inatructions. As stated in the video the assembly will be much easier if you have a ratchet wrench and a power tool.

First off - the "how to" video makes assembly super quick and easy. I didn't have to look as the instructions once. As for the machine - I love the stretches. I set it up in my home gym and now it's easy to add critical stretches between reps of weights and after cardio. Sure - you can always get on the floor on a mat (like I used to), but having a machine with a tilting seat makes getting into and out of stretches so much easier and more convenient. I wish I'd bought this years ago.

In the pre-COVID-19 world I was going to the gym a few times a week. I used the Precor machine at the gym and noticed that my back did not hurt. I could walk for over a mile and not have pain. Due to my age and many other health related issues I stopped going to the gym prior to the Ontario government closing them down. To make the story short, after a while my back hurt all the time. I could not walk to the back of the apartment building without sever pain. So I ended up buying the Nitrofit Limber Pro. I am so glad that I did. I thought that the Lower Back & Upper Back exercises would be my favourites. They are great but I found the Hamstrings exercise to the one the made my body the happiest. After only 1 week my back does not hurt as much. It is easier to put on my socks. When I do have pain, the Limber Pro is there to take it away. One surprise was the Calves exercises. I didn't realise how much I needed it or how good it would feel! It may just be coincidence but I no longer wake up with leg pain when I start to wake up. I have very happy with the Limber Pro. I just wish that I had purchased it much earlier. It was delivered much more quickly than Amazon's expected delivery date. It was relatively easy to assemble (there are a lot of parts). There is a video on YouTube that takes you through the assembly process. The Front Post Cover was broken during shipment. I contacted Medvibe. They responded within a short time requesting a delivery address for the part. I received the tracking number for the part the same day. The support department have been friendly and helpful.

Je bien satisfait de l'appareil. Un bon prix, beaucoup moins dispendieux que les autres modèles. L'appareil est robuste, flexible et facile d'assemblage. Je le recommande.

Could not have asked for anything more in terms of quality of product and online instructions they provide is great even when you are not "tool" handy!
