Since 4 months I’m doing yoga now and it helps me a lot to relax and to concentrate. Of course I’m glad to share you my favorite poses to do Backstage, while waiting for the barman to be ready, during breaks etc. Most are standing poses (since there is no mat next to the bar yet), working on concentration, relaxation, shoulders, neck, and the lower back. Namasté !
Edit March 2016: Updated with more poses of which also my favorite: Supported half dog
