About Flywheel Training

Flywheel training provides resistance but instead of using gravity, you use the force of your muscles to accelerate and decelerate a flywheel. One of the main advantages with using a flywheel machine like Exerfly is that your muscles are always under a constant load at all points and angles of the movement. Your muscles, tendons and ligaments constantly work and build strength over the whole range and angles of motion because there are no pauses or easy parts in the movements.

To overload the eccentric phase with the Exerfly, you can have a partner give additional force in the concentric phase, which then results in an overload in the eccentric phase. Other techniques are shown in the videos section.

Flywheel training is very safe because you can vary the resistance as you do the exercise to make it harder or easier.

Additionally, when doing squats using the squat harness the pressure is spread across your back and is much more comfortable than using a barbell.
