INTRODUCTION
What ​ ​ is ​ ​ it? The kBox is a self-contained, compact exercise platform for
various strength movements. It is a flywheel exercise device and
uses the moment of inertia to provide a high and variable
resistance in both the concentric and eccentric* movements of the
user.
​ *) concentric muscle action is when the muscle is 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 adjustable-length 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).
