The Velocity Trainer is the ultimate sprint training device! With a 24' long speed cable, the Velocity Trainer provides athletes with an assisted sprint up to 70 feet. You can literally teach the body to run faster than it normally can, and to accept new limits. This is an excellent speed training device for football, baseball, track, softball, any sport requiring sustained sprinting. The Velocity Trainer is one of the safest, most effective overspeed devices on the market. It features the Safety Loop System on one end and a durable Tow Vest that will help the athlete maintain correct running posture on the other. The rubber tubing is safely enclosed so that, should the tubing inside break, the athlete is protected.
