Exxentric kGrips

The Exxentric kGrip is an essential accessory to any flywheel device. It is comfortable, versatile, durable, light and aesthetical

The kGrip weights only 105 grams (about 0.2 lbs), avoiding wasting unneccessary energy on defying gravity like with a heavy iron grip. This transfers more energy into the flywheel for use in the eccentric phase. Also being able to adjust angles through the motions is very beneficial.

Its coating is designed to be highly comfortable, and top materials are selected for optimal durability.

The kGrip is perfect for many different pulling exercises like straight-arm lifts, hammer curls, deadlifts, high pull and row. Do the exercise using both grips with maximal effort and power or in single version for balance like in single-hand RDL or for rotational strength like in a single hand row. It is a typical accessory to any kBox system, but it can be used also for traditional weight training.

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}

Training Exercise shows Deadlift

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.

Training Exercise shows High pull

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.

Training Exercise shows Biceps curl

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

Training Exercise shows Triceps extension / over-head press

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.

Training Exercise shows Bent-over row

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
