Description
Inertia
The force in aย flywheel trainingย exercise depends on a combination of the intensity you work with and the selectedย inertia. With a higher inertia, the motion will be slower and more controlled, and your muscle will be able to produce a higher force. With a lower inertia, the motion will be faster which alsoย putsย higher demands on skill, balance and technique.
Usage
The inertia resulting from the size and number ofย flywheelsย you select impacts the training adaption you get. Together with your workout intensity, the inertia chosen decides yourย Flywheel Workout Zone, which can includeย strength training, power training, eccentric overload and warming-up.
For guidance on how to mount a flywheel onto your kBox4 or kPulley2 device, please watch our quick demonstration here.
Selection
Theย kBox, kPulley and LegExx can be equipped with two or four flywheels simultaneously depending on the device model. Additionally the Advanced Flywheel Knob can help to boost that capacity by two flywheels of a compatible size.
The flywheels are available in five different sizes:
- Extra Large: 0.070 kgmยฒ (only compatible with the kBox4 Pro, LegExx, LegFlexx and all kPulley devices)
- Large:ย 0.050 kgmยฒ
- Medium:ย 0.025 kgmยฒ
- Small:ย 0.010 kgmยฒ
- Extra Small:ย 0.005 kgmยฒ
The average first-time user typically starts with one large flywheel for most exercises on the kBox as opposed to one medium flywheel on the kPulley.
The medium and light flywheels can be used both on their own for high-speed exercises and weaker individuals (such as for rehabilitation), but they can also be used to fine-tune the inertia at higher loads. The Single-Turn Buckleย can help you get the most effectiveness out of an Extra Small flywheel.
