Variable Resistance
Variable Resistance
One of the most important advantages of flywheel training on the kBox is its ability to provide eccentrically overloaded training in a safe, practical, and efficient way.
Resistance Through Inertia
Flywheel training increases the effectiveness of your strength training by applying the inertia of a flywheel instead of simple gravity to create optimal resistance.
In regular strength training with weights, the load in the eccentric phase is limited to how much the weaker concentric phase can lift. As a result, the eccentric phase is rarely loaded to its maximum, and the training loses efficiency.
Unlimited Resistance Spectrum
Eccentric overload is when the eccentric force is larger than the maximal concentric force.
To reach your maximal force in the eccentric phase, you need to apply some method to get eccentric overload.
In traditional strength training with weights, achieving eccentric overload is challenging from both a practical and a safety point of view. The traditionally applied methods include:
- Help from training partners with lifting beyond your max in the concentric phase, as well as controlling yourmovement in the eccentric phase. These methods are often time-consuming and have a high risk of injury.
- Using certain weights stack machines, for example, leg extension by using both legs up and only one leg down, which is not a very functional movement.
- “Cheating” using auxiliary muscle in the concentric phase, but you often get less efficiency in the concentric phase and also increases the risk of injury.
The Flywheel Advantage
With flywheel training, eccentric training and heavy eccentric overload have never been easier or safer. Using the kBox you can use our methods to perform eccentric training with overload without help and also without the risks associated with traditional methods.
If you decelerate the flywheel in a shorter time than the acceleration phase, you will produce a higher eccentric force. You can also produce force in the concentric phase with auxiliary muscle and only use certain muscles in the eccentric phase to overload them. Read more.
With the addition of the kMeter wireless feedback system, you can easily measure the eccentric power and overload. Eccentric training is getting safer and less practically challenging as flywheel training gains momentum across the globe.
