Medicine Balls are made from highly durable materials making for a good user experience.
Please note that medicine balls are not designed to sustain high impacts against hard surfaces. As well as that may shorten the life span of your medicine ball. A medicine-ball (also known as an exercise ball, a med ball, or a fitness ball) is a weighted ball roughly the diameter of the shoulders (approx. 13.7 inches).
Often used for rehabilitation as well as strength training. Most modern medicine balls are made of nylon or dense rubber for better durability as well as user experience.
