Kynett Disc Set 2mm
Kynett Disc Set 3mm
The Kynett ONE comes standard with two 3mm thick discs. These discs are most commonly used in physiotherapy and rehabilitation. The 2, 3 and 4 mm discs can also be combined for even more resistance variations.
The resistance used for training is not expressed in kilograms but in a moment of inertia kgm 2 . Every object that can rotate about a certain axis has a so-called moment of inertia. The moment of inertia can be calculated from the mass and dimensions of the rotating disc.
Kynett Disc Set 4mm
The resistance used in training is not expressed in kilograms, but in a moment of inertia in kgm2. Every object that rotates about a certain axis has a so-called moment of inertia. The moment of inertia can be calculated from the weight and dimensions of the rotating disk.

How does flywheel training work?
Flywheel training is an unique innovation in sports and physiotherapy. Kinetic training is another term for flywheel training. Training is done with a rotating disc rather than traditional weights. The flywheel is triggered and accelerated during the concentric phase by pulling a ribbon. When the ribbon is completely unrolled, the eccentric phase begins; so much kinetic energy has been built up that the ribbon rolls back up, just like a yo-yo. The goal is to slow the flywheel down during the eccentric phase before restarting it with a concentric movement.
We are not used to this in traditional strength training because the strength we give in the concentric phase is also the strength we get back in the eccentric phase. Because of the constant load, you can also get more out of an exercise by training your muscles more intensively and quickly. Flywheel training maximises the effectiveness of each repetition because you can continue training at a lower intensity if you become fatigued.
Traditional strength training allows you to reach a maximum number of repetitions faster because you must let go of the chosen weights at some point.Flywheel training exercises are also more multifunctional because you must always maintain balance at the start of the eccentric phase, and therefore appeal to your abdominal muscles.
How do you make the exercise heavier?
Flywheel training involves using relatively light weights. The speed of the exercise determines the intensity more than the weight used, as it does in traditional strength training. The heavier the eccentric resistance, the harder the movement is deployed. Resistance discs of 3mm thickness (800gram), 4mm thickness (1200gram), and 5mm thickness can be used with the Kynett HOME (1550gram).
These can be combined, but they can also be used separately. The device can hold up to two discs at the same time. Heavier resistance discs of 6mm thickness (1660gram), 8mm thickness (1950gram), 10mm thickness, 12mm thickness, and 15mm thickness (2550gram) can also be used with the Kynett FIT, PRO and ULTIMATE.
