- A medicine ball is a weighted ball roughly the diameter of the shoulders (approx. 13.7 inches). Often used for rehabilitation and strength training, it serves an important role in the field of sports medicine. Medicine balls are usually sold as 2–25 lb (0.91–11 kg) balls and are used effectively in plyometric weight training to increase explosive power in athletes in all sports. Some medicine balls are in the form of weighted basketballs. - Wikipedia
