Multi-directional training has never been easier! Flexible rubber tubing provides resistance and assistance to your speed, agility, quickness, and change-of-direction drills. It’s great for explosive starts and acceleration, and is unmatched for resisted plyometrics for increased vertical jump development. The Multi-Speed features enhanced safety with our Safety Loop System. This unique, self-forming belt has no hardware to break or remove, and the rubber tubing is safely encased. Simply step into the loop, position the padding around your waist, and pull the choke toward you. The other end snaps to a padded waistbelt. NOTE: Trainer is black, not yellow.
