This part of the workshop (like HB2 and HB4) will be a pre-recorded video and last approximatly 15 minutes.
You can start the video within the scheduled time, when convenient for you.
The only "tool" you need is a chair without armrests.
The workshop is lead by Cornelia Köster, a Yoga teacher in Berlin, Germany: http://yogaflow-berlin.com/me.html
