Kyoku jime (息絞) is locking teki with your breath, in the video above I feel teki’s breath and harmonise with it. As they expand their chest, at the top of the cycle they will then start to breath out. As their breath expels from their body, apply aiki to lock their breath. So I apply aiki sage, as their chest exhales and contracts. The pressure of my weight stops their breathing and allows me easily apply a submission.
