The myo-therapy ball is used for myofascial release of the muscles in every area of the body. Different size balls accommodate different muscle groups and body sizes. Myofacial release greatly increases mobility and recovery time. Great for self treatment of trigger points. The 8� ball is appropriate for legs, and larger muscle groups.
The Myo-Therapyball is constructed of heat sealed, non penetratable EVA foam; preventing bacteria growth on the surface. EVA foam is built to withstand the demands of exercise and will not lose shape.
Does not contain Latex.
Comments about SPRI® Eva Ball, 8":
I was expecting a softer, spongey ball to massage sore muscles. The ball is hard as a rock. I returned it but probably wasn't worth the trouble [...]Do not recommend this product. [...]Will not order from this company again.
