The main speaker is Detlev Friedriszik, who was diagnosed with Parkinson's 17 years ago. Since then he has been fighting against the relentless progression of the disease, trying to help others with his knowledge and experience and always staying positive despite all the odds.

His credo is "Instead of waiting in the corner in an armchair for new medicine, become active yourself and keep your mobility for as long as possible with sport". Always looking for the most suitable type of movement for him, he came across the so-called Smovey rings 14 years ago.

Smovey rings are a comparatively simple piece of sports equipment, imagine a ring in which three or four balls always move in the opposite direction to the movement of the ring.
Detlev Friedriszik quickly discovered the positive influence certain exercises had on the progressive stiffening of his muscles and the reduction in his range of motion.
