INTRODUCTION
What is it?
The kBox is a selfcontained, compact exercise platform for various
strength movements. It is a flywheel exercise device and uses the
physics of inertia and mass acceleration (centrifugal) to provide a high
and variable resistance in both the concentric and eccentric*
movements of the user.
*) concentric muscle action is when the muscle action when being
shortened while an eccentric muscle action is when the muscle is
being elongated during action. In some literature, concentric and
eccentric is called positive (shortening) and negative (lengthening)
phase.
How Does It Work?
The kBox has an adjustablelength drive belt wound around a shaft
located beneath the platform. Different combinations of flywheels are
mounted on the end of the shaft.
Using hand grips or a harness attached to the Pulley, the User pulls to
accelerate the flywheel and then resists to decelerate the flywheel as
the Belt winds in the other direction.
A Drive Belt Length Adjustment Button allows for quick adjustment of
the Belt length for the type strength work desired. Push the button to
release and adjust length or just push button to automatically retract
the belt (Pro) or manually shorten it by pulling the loose end (Lite). An
extension belt is used for overhead work (for example military press).
