The Stroops Power Jumper is the perfect workout equipment for training jumps and landing. Due to the elastic resistance, a perfect stimulus is produced so that athletes engage muscles of the core, hip, legs and feet. In this way, you don’t only train muscles, but you optimize biomechanics as well. Simply attach the Slastix® from your belt to weight plates, dumbbells, or other heavy objects and begin your vertical training regimen— hurdles, jumps, lunges, etc. Includes two 60-centimeters Slastix® and four adjustable anchors.
