With the kBox, you work against the variable inertia of heavy steel flywheels, instead of lifting weights against gravity.

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.

It also offers a number of important practical benefits, including:

  • It is a truly versatile multi-purpose training device, for exercises training both upper body, core and lower body.
  • It is completely portable and easy for one person to carry or stove away.
  • Its kMeter app-based wireless feedback system can be used to measure and save actual power output and more.
  • Switching between drills and users is quick and hassle-free.
  • The kBox practically doesn’t emit any sound at all.

These benefits result in increased efficiency of training programs while lowering the total costs as compared to alternatives. Read more.
