Run-N-Chute

The Run-N-Chute® is the only resistance training parachute to be wind tunnel tested. The panels are 4 feet by 4 feet. It was designed to help athletes increase their speed and lower leg power. Engineered with one "lead" so you don't have to worry about lines tangling during your workout.
The Run-N-Chute includes a training manual and quick release belt that fits athletes of all sizes. Multiple parachutes can be added for more resistance.
Here's what Dr. E. J. "Doc" Kreis said about the Run-N-Chute® “The Run-N-Chute® does something for speed improvement that no other running tool does; it teaches an athlete to run and builds explosive speed and sprinting power.”
