OPTUM S.P.S. Speed Resistance Trainer

Exclusive! Develop optimum speed, power, and strength for any sport through functional resistance. The specialized rope-and-pulley system of this unique device generates a smooth and constant pull during sprint or plyometric drills. An integrated adjustment knob lets you set the resistance level from 4 lbs. to 1,000 lbs. and a 120' cotton rope gives plenty of length to perform true training runs. Set up is simple: secure the unit to a stationary object like a fence or goal post, attach the harness, and begin training.

Aluminum construction with rubber roller. Includes nylon harness and instructional training DVD by Tom Shaw.
