Jumps

Jumps are a dynamic version of a squat. Jumps develop power in the quadriceps (thighs) and Gastrocnemius (calves). The abdominal muscles are also active in the transferring of forces. Before performing the jump squat you should at minimum be able to perform 10 correct technique squats with 1/3 of your body weight. Its also important to have adequate core strength.

Functional Benefit

Muscles respond to the rate or speed in which they are contracted. Performing jumps develops power in the legs which is of benefit to sports involving speed. Power training can also burn energy at the same rate as heavy strength training without developing large muscles. More powerful smaller muscles might be desired by an individual for asthetic reasons or it may be a requirement of a specific sport such as long jump.

Another benefit of the jump is it trains the quadriceps muscle in the later stage of the movement just before take off. When performing a standard squat this range of motion usually occurs with minimal loading
