Wall Balls are made from highly durable materials making for a good user experience. Please note that wall balls are not designed to sustain high impacts against hard surfaces, but rather medium to low impact. As well as that may shorten the life span of your medicine ball.
A wall ball (also known as a weighted exercise ball, or fitness ball) is a weighted ball roughly the diameter of the shoulders (approx. 20 inches). Often used for rehabilitation as well as strength training. Wall Balls are essential to any cross training or functional training facility. The Wall Balls are double manufactured to ensure durability.
If you require a ball for high impact, then a Hyperwear Sandbell will be more suitable.
