The Advanced Flywheel Knob is intended for use with any kPulley, LegExx and most kBox4 machines, allowing your muscles to produce higher forces during your workout. In contrast to the rapid movements in explosive or ballistic training methods, the movement of your exercises will be slower and more controlled with higher inertia. This flywheel button can be especially useful for strong men, powerlifters and weightlifters and other similar types of athletes.
