Today's novelty was a lot of practice using the hips to increase power when delivering gedanbarai. We also did repeated kekomi practice and I was humiliated at my pathetic flexibility enough to resolve to do 30 on each leg at home each evening. We'll see how that goes.
At the end Sensei showed us a self defence technique which I think may be the most painful I've yet experienced: pressing down on the collar bone with the knuckles. It is insane how something so simple can be so devastating.
