Wave, Adjustable Psoas Muscle Release Tool, Carbon Black

For hitting my QL and digging in to my back extensors this does an exceptional job. Yes, you could use a yoga block and lacrosse ball but you can dig in much better with this. I use it daily and get good relief. I would recommend this product.

Where has this device been the last 5 years of my middle-aged life? As a former athlete that is trying to stay active and approaching 50, I have been dealing with a sore lower back and hip pain for several years. My hip has been bothering me so much that even the lateral move out of the car can be quite painful. I did some research on hip flexor, sciatica, psoas etc and decided it was time to try anything. At first, I just kind of laid on it, put pressure thinking it would help. It made a moderate difference as I put pressure where I felt the pain. But after a few days I went back to the Thrival website and looked at their "how to Thrival" videos showing various stretches and, WOW, what a difference! My hip pain is almost gone after some intense stretching sessions. For years I had been dealing with a tight hip, wondering if I needed hip replacement, when what I feel I really needed was just appropriate stretching. I am a convert for sure, and it is only a few minutes each night before bed. Now I am spending 5 minutes in the morning in my quiet time, and finding that my day is much more enjoyable now that I have less aches and pains. My dog was very intrigued as to what I was doing each day and possibly seeing how relieved I was after using my Thrival, she is now taking claim and using it as her pillow and head rest. Wanted to show images to depict size as it is small enough to travel with and sturdy enough to last a long time. Give it a shot, watch the videos and find the relief you have been looking for.

I cannot say enough good things about Thrival Muscle Recovery! After struggling with persistent low back pain, I was honestly surprised by how quickly and effectively this worked. Within a short time of consistent use, my pain was noticeably reduced, my mobility improved, and I finally felt real relief. What makes Thrival even better is how easy it is to use. The design is simple, intuitive, and incredibly effective. The YouTube instruction videos are clear, professional, and easy to follow, which makes it perfect for beginners and experienced users alike. I never felt unsure about what I was doing—and that made a huge difference in getting results safely. If you’re dealing with low back pain, tight muscles, or recovery issues, Thrival is absolutely worth it. It has truly been a game-changer for my pain, my movement, and my quality of life. I highly recommend it to anyone looking for real, effective muscle recovery and pain relief!

I bought this for my psoas because running turns my hips into concrete. Turns out it also works on pretty much everything else that complains after a long run — glutes, lower back, and anything nearby that’s feeling dramatic. The adjustable width actually matters. I can make it gentle or “okay, message received” depending on the day. It’s uncomfortable in a productive way, not a regretful way. This is actually my second one — I gave the first to a running friend who refused to give it back. After a few weeks, my stride feels smoother and my post-run stiffness has definitely backed off. Solid little recovery tool for runners who collect tight muscles like souvenirs.

Definitely a product that works as advertised. It does take a little time to figure out exactly where to lay on the device but once you get used to it, it is a piece of cake. I really like using it for my glutes and my calves, especially I haven’t been as lucky releasing my back from the front, but I’ll keep trying. I think it would be nice if it included the soft covers so I may purchase those separately. Otherwise I would give it five stars. Definitely a value for the money when compared to other alternatives.

It's too large to get really deep behind the bone and into the muscle. Note that having both sides on it points the wrong direction but is a good "warm up." After using both sides you then have to take off one side and then work it inside-out to get deeper behind the hip/pelvic bone. Even so, it helps so 3 stars.

Wow my chiropractor told me to get this last year and i had my doubts that it would work and low and behold this apparatus works!!!! It was Instant relief for me!!! I would recommend it 100%

A friend lent me this device when I was dealing with back pain, and I was immediately impressed by its simplicity and versatility. The instruction booklet is excellent—clear, concise, and easy to follow with helpful pictures. I liked it so much that I ordered my own the same day, and it was delivered within hours! The adjustability is amazing, reaching muscles that foam rollers and massage balls can’t touch. After just a few sessions, my hip and back tightness eased noticeably, and my mobility improved. Lightweight, sturdy, and easy to store, this has quickly become my go-to recovery tool. Highly recommend!

Decided to upgrade from a massage foam roller and try out the Meat Grinder, and no regrets. It's more expensive but well worth it. Since it's adjustable, I can target my shorthened iliopsoas very well even tho it's deep down, and get quick relief. Also tried on other muscle groups as per the booklet and felt the same nice relief. Hmm maybe this can replace a massage therapist... Gonna order the upgrade parts to see what else this device can do.

Nice tool. I have a professional massage gun, but I actually find myself using the thrival wave more often.

Bon outil d’auto-massage. Il fonctionne bien pour les fessiers, les hanches.

I been a user of the Pso Rite for couple of years..and though its a great product and works well in my Psoas..I wanted something that can be adjusted to my body size and frame..enter the Thrival..at 1st I was skeptical about it..but once I used it..omg..its even better than the pso rite. It so much more versatile. Able to adjust to my Psoas, lower back, mid back, shoulders and neck and even target my calves and anterior shin muscles . 1 product for whole body. A total recovery system. No need to get separate tools for different body areas. Pso Rite u have a real competition in the Thrival. This product can bring it home.

I've been using it for my psoas, glutes, and shoulders and it's been pretty good releasing the tight muscles. I've seen other reviews on the durability but so far no issues yet.
