Our coaches

The FLEXVIT Coaches

Training with bands is incredibly fun, very varied, maximally specific and extremely effective. On the one hand, this should and will be expressed in our training courses. On the other hand, it places high demands on the mediating persons. That’s why FLEXVIT works with coaches who are experts in their fields and have years of their own experience with bands because they use them in creative and functional ways in their workouts with patients, clients or top athletes.


Tim is the developer of the FLEXVIT Bands and owner of the Flexible Sports GmbH behind it. He holds a degree in business administration, is a trained sports manager and completed an executive MBA at one of the renowned British business schools. He also worked internationally in the sports industry. Tim looks back (joyfully and almost injury-free) on a 50-year partially semi-professional career in soccer, which he is still trying to extend through functional band training. His greatest success was a bronze medal at the 1993 Universiade in Buffalo, USA.

He is not a fitness coach, but he does have the UEFA A license in soccer, during which he also started thinking about better bands for athletic training. With his experience as a player and trainer, he accompanies the developments of the FLEXVIT trainings as an advisor (and sometimes as a pre-tutor).
