Exxentric Squat Hip Belt

The Exxentric Squat Hip Belt is an essential accessory to the kBox. It is lightweight but strong, one-size and developed for flywheel training

The Exxentric Squat Hip Belt offers a practical alternative to the more advanced Harness, loading only your lower back (see comparison). The Squat Hip Belt is developed and tested specifically for the kBox, making it the ideal entry level attachment for squat and lunge exercises on the kBox. The belt comes in one standard size, suited for users ranging from XS to XXL, with an inner diameter range from 82 to 130 cm.

Physical Principles

With flywheel training (also known as isoinertial or yoyo) instead of lifting a weight against gravity, you accelerate or decelerate a flywheel. This way, the force required in each motion is variable as it is based on the inertia and the kinetic energy of the flywheel.

Physiological Advantages

Flywheel training offers many advantages over traditional strength training. The resistance is variable and unlimited. Eccentric overload can easily be achieved as well as mobility, ergonomy and economy.

Scientific Evidence

Multiple academic studies have provided support for flywheel training in recent years. We present a selection of some of the more important studies in the field.

{tab Training Exercises}

It could be a regular deadlift or stiff-legged deadlift. The experience of the eccentric phase in the #kBoxDeadlift will be new for most people. A nice exercise for lower back and hamstrings. Read more

High pull
Can be a total body workout on the kBox thanks to the variable resistance and eccentric overload. Kick in with the legs and the eccentric phase will kick you back. Works deltoids, trapezius and arms in the regular setting and most of your upper body and core in the CLAC overload setting.

Biceps curl
With the Exxentric ultra light bar, this will be your new favorite exercise. Forget giving the biceps 12 sets in the gym. The kBox will do the work in 3 maximal sets with eccentric overload. Read more

Triceps extension / over-head press
Slow and heavy with high force development with some core strength added. Perfect for a basic exercise to build strength and power in more complex exercises.

Bent-over row
After a couple of sets of rowing with eccentric overload you won't be able to go back to the traditional weights. It is a heavy exercise but still with a lot of power and motion, especially in the eccentric phase. It strengthens upper and lower back, shoulders and arms. Read more
