FLYWHEEL TRAINING
Practical Advantages
Whether your goal is to improve athletic performance, prevent or rehabilitate an injury or improve your general health and fitness, flywheel training and Exxentric training devices offer a number of important advantages.
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.

Applications
Exxentric products are being used by athletes and therapists for a wide range of flywheel training applications. Understand the benefits in your field. Check out the different sectors like Performance, Fitness, and Medical where you can already find Flywheel Training being implemented!
