The SKLZ Speed Chute resistance sprint trainer helps athletes of all levels maximize their acceleration and top-end speed through progressive resistance and overspeed training. It is designed with built-in mesh panels to prevent strings from tangling but also to help stabilize the equipment during your workout. The device features a 360° rotation belt to let you move in any direction while the quick-release buckle allows for mid-stride, shot-out-of-the-cannon sensation so you can improve your stride length and frequency.
