Product Description

With this 15 mm disc set is it possible to train very hard! The 15 mm discs can only be used in the Kynett FIT, PRO and ULTIMATE Flywheel and not in the Kynett HOME and ONE Flyhweel!

The resistance used to train is not expressed in kilograms but in a moment of inertia kgm2. Every object that rotates on a certain axis has a so-called moment of inertia. The moment of inertia can be calculated based on the mass and dimensions of the rotating disk.

How to change Kynett Flywheel discs?

Step 1

With one hand you hold the disc and with the other hand you loosen the quick release button.

Step 2

The quick release button can be removed. It has a spring-loaded mechanism, simply pull the quick release button outwards. and the quick release button is released.

Step 3

Grab the disc with both hands and slide it off the center axle. Replace the disc with another disc. A thicker disc in mm makes the exercises more difficult and slower; a thinner disc in mm makes the exercises easier and more explosive. Reattach the replaced discs with the quick release button and close the door.

Advantages of Flywheel Training

    Muscle hypertrophy
    Strength gains
    Injury prevention
  2. Increased muscle activation: Flywheel training has been shown to elicit higher levels of muscle activation compared to traditional weightlifting exercises, This increased muscle activation can lead to improved:
    Muscle development

Flywheel Training vs Traditional Training

Load Capacity: Experience the difference in load management. Flywheel Training offers adjustable resistance that adapts to your strength and needs, allowing for progressive overload without the hassle of constantly adding or removing weights. Say goodbye to plate swapping and hello to streamlined, efficient training.

Repetitions: Maximize every repetition with Flywheel Training, each repetition engages your muscles throughout the entire range of motion, ensuring optimal muscle activation and stimulation. The flywheel challenges your muscles in both concentric and eccentric phases, resulting in superior gains and enhanced muscle development.

With dumbbells and barbells the resistance is constant, with Kynett Flywheel Training Equipment the resistance is adapted at every instant and proportional to the force developed. The greater the force, the greater the acceleration with which the flywheel reacts.
