Improve Your Skiing. With Exxentric Devices.
Need help?
Elevate your downhill performance by developing sport-specific lower body strength and endurance while preventing injury with the unique benefits of flywheel training.


A Stronger Skier – Is a Better Skier
The variable resistance and capacity for Eccentric Overload of flywheel devices make them uniquely applicable to conditioning athletes to the demand experienced during downhill runs.
By letting you train targeted ROM with peak output and overload the eccentric phase – flywheels prepare you to safely and effectively absorb, transfer, and control the lateral and vertical forces you experience in competition.
