All balls are 14” in diameter, moisture resistant, and are made from 70% post-consumer recycled materials. The design and construction ensures that they will remain dimensionally stable and balanced. Our trade secret and craftsmanship guarantee that each ball, regardless of weight, has a friendly feel and will absorb high velocity impact, making for a fun and vigorous workout.
All models of the Dynamax Medicine Ball have undergone extensive testing and are designed to endure repeated impact in all athletic training and fitness situations.
The seams on a Dynamax Medicine Ball will not fail unless the product is abused by repeated impact against a rough, aggregate surface or slamming the product on the ground from overhead. Dynamax Medicine Balls have been tested to withstand repeated impact against any relatively smooth, reinforced wall.
