Plyometrics are bursts of bounding, jumping, lunging, and many other movements, designed to be short powerful bursts of energy. Start by jumping as high as you can, as you land soften your knees and squat, immediately jumping back up. There should be no rest in between a jump and a squat, make sure you remain in one stationary location. Stand on a line or draw a chalk line on a driveway to make sure you are not traveling.
2.Jump Rope. Is both cardiovascular and coordination driven, using your core and your lower body.
