Adds approximately 32 pounds of resistance at 100 percent elongation. The Economy 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 performing jumps upward and helps pull the athlete back to the ground on the descent. To increase resistance, simply secure the end loops further away from the jumper. The pull back to the ground allows the athlete to perform more jumps in a shorter period of time. The product includes a shoulder harness, two 45 inch tubes on each side with nylon loop anchors. Since 1986, Power Systems’ passion for fitness has been fueled by our customers.
