kBox: Our Signature Product

The kBox is our very first, and to this day, best selling product line. Trusted by thousands of athletes, coaches, and home users around the globe, the kBox has proven itself as the most versatile strength training solution on the market today.

Offering over 70 different exercises for the whole body and full kMeter compatibility, the kBox is designed to elevate the performance of any athlete. Choose between the kBox Active, Lite, and Pro to find the model that fits you best.

kBox Adapts To Your Strength

kBox uses flywheel training technology to offer variable resistance that automatically adjusts the load to user input. Train with perfect resistance on every rep and achieve your goals faster, whether you are a professional athlete or just want to get in amazing shape.

While kBox can be used for a range of exercises for upper and lower body, Squat and Deadlift variations are where it really shines. Especially, once you start applying eccentric overload!
