Isokinetic Leaper exercise equipment develops fast-twitch muscle fibers. This results in jumping higher, running faster, and increasing overall explosiveness. The key to our fast but safe workouts with our power training equipment is our unique isokinetic positive (concentric) resistance mechanism.

With the Leaper we have virtually eliminated the negative (eccentric) resistance allowing an athlete to do 30 positive accommodating isokinetic resistance power squat reps in 30 seconds. This would be dangerous and impossible with traditional weight training.
