Medicine balls develop coordination and balance.
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 and strength training.
Doing exercises when off-balance helps to work deeper muscles, the ones that are vital to maintaining good posture. The result will be that you can exercise safely (better core stability, stronger back), as well as feeling the benefits in your everyday life.
