{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 or watch video. #kBoxDeadlift

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 . Watch Video. #kBoxHighPull

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 or watch video. #kBoxBicepsCurl

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. Watch video. #kBoxTricepsExtension

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 or watch video. #kBoxRow
