About the kBox
Train Up To Your Potential
With the kBox and kPulley, instead of a fixed load determined by gravity when lifting weights, you work against the variable inertia of heavy steel flywheels determined by the effort and energy you unleash into the device.
Engage Every Muscle
These training devices are truly versatile and serve multiple purposes, allowing you to engage your upper body, core and lower body with a wide variety of exercises.
Keep The Gym Nearby
It is completely portable and easy for anyone to carry or stove away.
Get Real-Time Feedback
Its kMeter app-based wireless feedback system can be used to measure and save actual power output and more.
About the kBox
Scientific benefits
The kBox is renowned for its genial application of eccentric overload in regular training as well as its variable resistance, both backed by growing scientific support.
Mix and match
Switching between drills and users is quick and hassle-free.
Silent
The kBox practically doesn’t emit any sound at all.
Lower cost
These benefits result in increased efficiency of training programs while lowering the total costs as compared to alternatives.
