Ergonomy and Usage

The Harness puts the pressure on the shoulders when you have a correct, upright position. If you tend to lean forward it moves the pressure down towards the lower back and shortens the lever for the force and reduces torque on the lower back, resulting in less bruises and a less sore back. The latest revision of the Harness also includes shoulder pads for further improved ergonomy.How much would you be able to squat in the gym if your technique was not an issue? Imagine if you didn't have to worry about balance, bruising on the shoulders, straining your back and needing a spotter. You would probably be able to squat a lot more.The Harness is made of strong but still soft and light-weight material and weighs just 950 g for the XXS size and 1300 g for the XXL.

{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.

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.

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.
