An on-the-ball workout

It's small but packs a big punch. A medicine ball is a weighted ball used to whip your body into shape, without taking up much space. It's similar to standard weights, but with the medicine ball you only need one in order to get in a full workout. If you're a fitness newbie, start with a 4-pounder (sold at most sports stores). Advanced fitness junkies may choose to use a 20-pound ball.
