XBT® is an innovative, mobile, and extremely versatile exercise machine
for functional training, fighting, boxing, and group fitness.
It consists of a comfortable belt, two cable pulls with steel springs, hand
and foot loops. To achieve an effective full-body workout, attach the cables
to your hands and feet.


To achieve an effective full-body workout, attach the cables to your hands and feet. Every time you make a movement, you will be working to overcome the spring force. You’ll feel the resistance thereby training your upper body and legs. The integrated adjustment mechanism challenges both beginners and experienced professionals alike to overcome their personal limits. Whether you’re working on knee bends, kicks, punches, jumps, or other functional exercises – you will simultaneously improve your strength, speed, and endurance.

Feel the resistance with the one-of-a-kind XBT®!


The Do It Academy has already developed XBT® SPEED and
XBT® SLOWMO, two course concepts that guarantee fun,
sweat, and sore muscles.

THE XBT story

The product idea of a versatile cable system for the gym has its origin in the first cooperation of our sales partner Powrx and our mastercoach Klaus Kirsch.

Klaus Kirsch commissioned Powrx to find high quality resistance bands for his fighting training. In the further course of the project, Klaus Gremmelspacher from Powrx came up with the idea of replacing the resistance bands with spring balancers, similar to the product Pro-X Walker, for versatile resistance training. On the initiative of Powrx, a meeting with Carl Stahl Kromer (producer of the Pro-X Walker), Powrx and Klaus Kirsch was arranged to promote the idea. Then Klaus Kirsch assembled the first prototype with spring balancers from Carl Stahl Kromer, Made in Germany.

This version was ultimately the basis for further product development, which was carried out and successfully completed by Carl Stahl Kromer, incorporating the expertise of Klaus Kirsch.


Due to the close cooperation and the input of all three parties, our XBT was finally born…
