Build explosive power and jumping ability! PER4M Jump Trainer maximizes your vertical and horizontal explosiveness by strengthening quads, hips and glutes. Increase lower body dynamic strength by adding resistance to drills and training workouts. 

The padded Adjustable Belt and Adjustable Ankle straps won't irritate skin during training; heavy-duty padding and construction won't rip; adjust for a tight/secure fit. 

Heavy-duty construction means products last longer under intense training environments. 

The backpack carry bag is large; carry the Jump Trainer and belongings wherever you train.
