Plyometrics are exercises that use a muscle contraction immediately after the muscle has been stretched. These exercises increase power or explosiveness. Power is speed x strength. Plyometrics will increase power thereby increasing speed and vertical leap. Plyometrics can be hard on the body so don't over do it. If you feel excessive soreness or pain, then you need to take a rest. It is also a good idea to stretch before performing these exercises, so that no injuries occur. Sprints and long distance running will also help optimize this workout and increase vertical leap further.
