Supported by scientific evidence

Flywheel training increases the effectiveness of your strength training by applying the inertia of a flywheel instead of simple gravity to create optimal resistance.

Physical Principles

With flywheel training (also known as isoinertial or yoyo) instead of lifting a weight against gravity, you accelerate or decelerate a flywheel. This way, the force required in each motion is variable as it is based on the inertia and the kinetic energy of the flywheel.
