Take your exercise routine to a new level when you work out with a medicine ball.  A variety of weighted balls are used to build muscle, strength and help you tone.  Medicine balls are between 2-25 pounds and the standard ones are approximately size of a basketball. They come in different textures and even different sizes, depending on your needs.

While you might think that medicine balls are a new exercise fad, they are actually one of the oldest types of exercise equipment.
