Get explosive training anywhere with the improved Power Systems Economy Power Jumper. The Power Jumper is a plyometric training device designed to improve jumping ability and reaction time with the ground. It allows the athlete to do a series of repeated resistance jumps. The latex tubing provides resistance when the athlete jumps upward and helps pull the athlete back to the ground on descent. To increase the resistance, simply secure the end loops further away from the athlete. The pull back to the ground allows the athlete to perform more jumps in a shorter period of time. The user friendly design and portability make it ideal for training athletes in role-specific situations.
