What is Flywheel Training?
Unlike traditional weights, Flywheel Training uses inertia to create resistance. The harder you pull or push, the more resistance the flywheel generates, automatically adapting every repetition to your effort. This allows you to train the lifting (concentric) phase with maximal intent while accessibly and safely emphasizing the lowering (eccentric) phase, helping you build strength, power and muscle more efficiently.
