Christina Leon shows you a few very basic exercises which involve hopping onto or using a Step Bench to elevate the heart rate. Plyometric exercises are very intense since they involve explosive power or leaving the floor. A jumping jack is a plyometric move as is a push up with a clap. When performing plyometrics it is important to have a cushioned landing area, like gym mats, so that you protect the joints in the ankles, knees, hips and back.
