The main portion of the video seems to be a translation from a clinic with some fairly high level riders.
The conversation is in German with a voice-over English translation. The first 45 mins seems to be a clinic with some high level riders.
Most (if not all - havent watched the whole thing) of the exercises do NOT use the chair - they are either done sitting in a regular chair, or lying on the ground.
I WILL say that you could see a definite difference in the horses' ways of going as he loosened each rider up.
I will also say that I tried a couple of his 'loosening' exercises and could feel a difference.
I will ALSO say, however, that many of the positions look extreme enough that if the exercises were not performed with control, or if one had an underlying medical condition, that one could hurt oneself pretty easily....
