Harness
The Exxentric Harness is an essential accessory to any flywheel device. It is both comfortable and lightweight.
The Exxentric Hip Belt offers a practical alternative to the more advanced Harness, loading only your lower back (see comparison). The 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 two sizes, catering to users ranging from XS to XXL. The standard size has an inner circumference range from 82 to 130 cm and weighs just 280 g, whereas the small size has an inner circumference range from 60 to 110 cm and weighs 212 g.
{tab Function}
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.

Harness Size Guide Explanation
{tab Training Exercises}
The kBox gives you infinite opportunities for effective exercise. Here are some of the best flywheel training exercises you can do with the kBox. Don't let gravity hold you down. Ever.
Squat
The king of exercises. Performed with the Exxentric harness to give ergonomic benefits and maximal strength development and results even if the technique is not perfect. It is a great workout for all of the lower body.
Split squat
One drill we know many of our users do in many variations and under different names, Bulgarian split squat or Rear Foot Elevated Split Squat (RFESS). This exercise targets Gluteus and Hamstring more and Quadriceps less than a regular back squat.
Lateral squat
Gives enhanced performance in running, jumping, sprint, skiing and skating. Activates the gluteal muscles to an extent that is impossible to achieve with traditional weights. It is a very good drill to activate gluteus medius and also prevent injuries to the ACL.
Lunge
Without losing the edge of balance and postural training, this exercise really boosts your force development in the lower body.
Hip extension
An underused exercise that really targets the upper hamstrings. Suitable for both rehabilitation and performance.
Single leg RDL
If you want to really load a single leg RDL (Romanian Deadlift), the kBox version is your choice. Try variations using contra- or ipsilateral arm and feel the difference in the working leg and the core. The variable resistance will give you a smooth and hard contraction all over the range of motion.
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.
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.
