Stealth Align Foam Roller - Deep Tissue Massage - Align The Back - 24"L x 8"W x 8"H - Maximum Range of Motion

I am active, work out regularly. I also have scoliosis in my back, arthritis in my knees and feel sciatica in my legs probably coming from my pinched S1 nerve. In addition to working out, strengthening my muscles, stretching and yoga, I also use a foam roller on my legs and my back. I tried several foam rollers and liked them but there are limitations. I used a long straight cylinder shaped foam roller, which works pretty well for legs. For some applications a short foam roller is better. But because of the big surface, the pressure of cylinder rollers is not as strong and after a while, the pressure was not big enough anymore for me. I also used a short cylinder shaped foam roller, and another one had a pattern to increase the pressure. The big limitation is the usage for the back because the standard foam rollers are not good for the back. If I roll straight on them, I would roll on my spine which is not good. A good foam roller should roll left and right of the spine and not on the spine. I tried to angle my body on the cylinder shaped foam rollers to roll the sides left and right of my spine but that is pretty laborious with little success. Then I tried the foam rollers which are shaped like two balls with allow to roll left and right of the spine without putting pressure on the spine. That worked ok for the back, but I felt that these are not very stable and the roll effect is random. Also the ball shaped ends of these foam rollers are often small so that rolling on them for the entire back felt weird. Then I saw this foam roller from MUUVSPORT with the two foam wheels which also have over 50 pressure shapes (in diamond shape) to further increase the pressure. I ordered it and it arrived a few days later (it does not seem to apply for Amazon Prime) but it was there in around 5-6 day. I used it on my back and just after a few rolls on my lower spine up to my neck, I felt the difference. This foam roller is super stable and rolls perfectly. Because of the bigger size, it is very easy to roll the entire back in one simple, stable, straight roll without twisting my upper body. So you can easily roll forward and backward and you easily cover the entire back. The big wheels allow that. The two wheels apply strong pressure on the area left and right of my spine while my spine stays untouched. Perfect! The two wheels with its pressure points apply great pressure on the fascia and increase my flexibility and reduce the negative pull forces which are the source of my back pain. My back feels completely stretched and relaxed after I roll it a few times. It does not hurt. It feels awesome. This roller is not small. It is big (7 3/4 inches diameter and 23.5 inches long). It looks like the M1 Abrams of foam rollers and I know that I will never go back to a straight foam roller. This foam roller is not cheap ($39.50 when I bought it) and costs a little bit more than the straight foam rollers but believe me: you will never want to use the straight foam rollers again after you used this one, especially if you want to roll your back. Straight foam rollers work ok for legs but for the back they are not good. But even for legs, this foam roller is much better because it applies more pressure (without hurting). Wonderful product with superb design and quality. One comment about the shape. The ends of the roller are cone shaped. But they are not touching the ground when rolling. They are just there in case you wiggle to one side, to give you immediate support. The foam roller also comes with a poster which shows the key rolling positions (I think the poster is shown in the product photos). One drawback is the size. It is not well suited for travel. For that I will need to use a small two-ball-shaped foam roller. But for home, this is the best foam roller that I have ever used. I am male, 6ft and the size fits perfect for me. But I believe that this roller fits for all sizes.

I wrote this company (MUUV) an email before I purchased this to ask if the product contained any of the manufacturing chemical "Thiourea", to which I'm allergic. In a day, I received an authoritative, straightforward answer: --- Hi Sierra, Here is some information to your question. Our EPE products do not contain thiourea. Thiourea is a sulfur containing derivative of urea. Some compounds used in textile processing contain thiourea. Other compounds like ethylene thiourea are used as curing accelerators for certain types of elastomer adhesives. Again, our EPE products are free of thiourea. We hope this answers your question. Thank you, The MuuvSport Support Team --- So I went ahead and ordered this roller. As promised, it's not triggering any touch allergic reaction for me, nor does it smell like formaldehyde, which is a deal breaker for me. At least half the fitness equipment out there offgasses formaldehyde or puts chemicals onto your skin, or both. It's pretty brutal looking in the picture, but it does have give to the foam and the bigger diameter makes the roller gentler to use than the six-inch rollers can be. It's perfect for rolling the spine of a healthy person. As far as other rolling uses, I haven't yet tried them. I'm hoping this roller lasts for a long time. I think you could crack the foam in two over your knee if you really tried, but with reasonable care, this should stay in nice condition indefinitely. Potential improvements: Maybe make a silver one in softer material, scaled down 10% for the ladies. This thing could work for a professional linebacker, which says something about its quality. Also, a softer one might be nice for physical therapy for elderly arthritis patients like my father.
