From the brand
How did we get our start?
Our own physical therapy journeys suffered as a result of the tools available, leading to the improvement of the available foam rollers on the market, and finally to this product.
What makes our products unique?
Our products are engineered from the ground up. We invest heavily in R&D to rethink the size, materials, construction and densities of everything we make.
What problem are we solving?
Smooth rollers only compress muscles, our patented texture allows for deep tissue penetration and truly effective massage.
Our journey began with a personal need for effective muscle therapy, leading to the creation of revolutionary products designed to penetrate deep into soft tissue, flush out lactic acid, and alleviate muscle adhesions. What sets us apart is our commitment to innovation, investing in extensive research and development to engineer products from scratch. We prioritize user experience over everything else, ensuring proper technique with our 4K eBook.
PATENTED TECHNOLOGY: Relieve sore muscles, perform deep tissue massage and acupressure with our medium density massage roller, great for relieving back pain. The patented projections extend deep into soft tissue and fascia to break up knots and calm tense muscles in your neck and back
SUPERIOR QUALITY: Our textured foam roller mimics the hands, fingers, and thumbs of a physical therapist, but in the privacy of your own home. It features a super-strong and lightweight core, and is entirely wrapped in BPA-free closed cell EVA foam for a premium look and feel. The density of the projections, and their unique shape and pattern offer effective results with a comfortable level or penetration into the soft tissue and muscle fascia
TARGETED RELIEF FROM PAINFUL ADHESIONS: Exceptionally suited for a comfortable yet effective deep tissue massage, our product is designed from the ground up to flush lactic acid from muscle tissue, enhance pre- and post- workout stretching and recovery. It is firm enough to offer therapy to the muscle groups on either side of the spine, yet soft enough to not hurt the spine when rolled directly
UP YOUR STRETCH GAME: Our massage roller offers three massage zones that allow you to dial in your massage intensity. The smallest projections are like a massage therapists finger tips, the larger projections mimic the thumbs, and the largest ones feel like the base of the palms. There is no hard plastic in our product, so you won’t crack it, and it supports an incredible amount of weight so it won’t deform or flex
QUICK AND EFFECTIVE: Foam rolling for just 20 minutes after exercise, and again at 24 and 48 hours has been clinically proven to reduce recovery time by 20%, increase flexibility by 10%, and reduce soreness by as much as 30%. They have also been shown to decrease the risk of injuries in the first place

Great quality and very effective!
This is excellent quality and super durable. It still seems brand new after years of consistent use. I expected the foam to be spongier, but it’s actually for the best that it’s so firm because it’s easier to control. Although the spikes look a bit intimidating, the surface feels surprisingly even when I’m rolling flat, and I can also target specific spots simply by adjusting my position. By turning my torso to the side while rolling my back, I can even work the knots under my shoulder blades, which is fantastic since that’s mainly why I bought this.It’s also proven quite effective at relieving tightness and cramps I often experience due to Restless Legs Syndrome. Rolling my calves and thighs before bed really relaxes my legs, which helps me fall asleep much faster and wake up without soreness. My best friend owns one too and swears by it after vigorous workouts. It can even be used purely for pleasure, as the massage function feels enjoyable all around.Best of all, there are plenty of ways to utilize it regardless of one’s fitness level. I have poor upper body strength but still found many easy exercises that alleviate my back and leg issues. There are tons of great guides online. I suggest securing loose clothing and long hair beforehand, and I’d also recommend starting slow and taking care not to overdo it. This is an extremely versatile and valuable tool when used in moderation, but going too long or hard, especially on a single area, can result in bruising. Once I began limiting sessions to 15 minutes, I had no further issues.My only complaint is the length. I’m a woman with a small frame, and this is the same size as my upper back from shoulder to shoulder. I struggle to stay perfectly straight while rolling my back, so I start falling off the side as soon as I become crooked. With a few extra inches of leeway, I wouldn’t have to stop and reposition so often. That’s just a matter of convenience though. A longer model wouldn’t be any more effective, and I don’t plan on replacing this one until absolutely necessary because I’m so satisfied with it otherwise.

Really nice just a little small
Works well brings relief to the tight feelings in muscles. I wish it was a little bigger. The ridges help more than the solid rollers for me. Itâs super firm which is fantastic as well. Recommend for sure!

Small BUT Mighty
This little jewel is amazing for relieving tight cramping muscles. I have had surgery on my lower back and when I’m doing things around the house, lifting, pulling around different heavy objects and bending, up and down a lot, my back begins to tighten so badly, I cant hardly move. I get this little roller out and place it on the lower section of my back and then with my knees up, and feet on the floor, I pushed my body back and forth so the roller moves up and down on my lower back. There is just the perfect amount of pressure to stretch my back, which in turn releases the tight prrssure . I may do this several times in a day. Whatever it takes to relieve that pain and pressure. The first time I did this, it hurt a little but, once I realized I needed to relax to let the roller work as intended, it felt incredible. So take a deep breath and roll as you breath out and you will not be disappointed in this roller. Just RELAX and you will have no regrets about purchasing this roller. I’ve found it to be very sturdy but, not so hard that you can’t relax. That’s the key to making it work for you. I’ve used longer rollers and they work great also but, this one is great especially for travels so it’s a win win for me The picture I posted will show you the actual size as to how it fits into your lower back. Give it a try. You can’t go wrong with this roller
