What is Exerfly?

Flywheel training is a method of strength training where users generate resistance using the inertia of a flywheel instead of traditional gravity-based resistance training.

By accelerating and then decelerating an inertial disk, the user generates resistance at all phases of the movement, allowing high force outputs and eccentric overloading without the heavy weights. Exerfly users have shown significant increases in strength, speed, and explosiveness.

The Flywheel's constant resistance has proven to increase muscle hypertrophy and convert fast-twitch muscle fibers, magnifying force absorption and production.
