We invented Thrival because no other Psoas release tool really worked all that well. We soon realized that the problem with most self-manual therapy tools is that they aren’t adjustable for different size bodies. Thrival is. And adding different shaped attachments lets us use Thrival on all parts of the body. That’s how Thrival became the one tool for “every-body”.

The key to Thrival’s superior deep tissue massage is the narrowness of the arches and the ability to adjust to a person’s body. The narrowness of Thrival’s arches reduces the surface area that your back rests upon, which in turn creates a deeper massage. Furthermore, it is necessary that the product adjusts to your body so that you can effectively apply the pressure to the right area. The Thrival Back Stretcher adjusts both extremely narrow and wide so that it will fit every body and every muscle group.
