The kBox is one of the most advanced tools for strength and rehab training, used by professional athletes, coaches, and therapists around the world. Unlike traditional weights, it uses flywheel resistance — meaning the harder you work, the more resistance you create. This makes training both safer and more effective, especially for developing eccentric (lowering phase) strength.

• With unlimited, auto-adjusting resistance – the kBox let’s you maximize your training intensity without compromising safety.

• The kBox replaces your entire gym on a small footprint by offering more than 70 exercises for the upper and lower body.

• With kMeter compatibility you can track, measure, and compare training data to optimize your results and progress.

• At only 10kg (22lbs), the kBox Lite is portable enough to bring with you wherever you go. Turn the world into your gym!
