The Versapully is a pully that combines velocity, power, and motor skill. The Versapully is a functional training device that simulates an athletic situation. The Versapully works with a flywheel. The wheel makes it possible to train concentrically (strength training by which the muscle gets shorter) and eccentrically (strength training by which the muscle gets longer). The pully is connected to a screen, allowing for the monitoring of results and progression.
