Started with a walking-breathing drill – five of us walking quite quickly and continuously in a circle, breathing in and out on consecutive steps, then two steps per inhale and exhale, building up to 8 steps and back down. Then holding the breath while walking. Then the leader has to hold their breath and head off at a faster pace until they catch up with the end of the group. Then the same but have to exhale all the air first – surprisingly stressful, which of course was the whole point.
Then putting increasing, sgifting pressure on your partner lying on the ground. Worst place is the thigh. Have to breath and relax through. The the same, have to feel the pressure and roll away staying close. Then same with various side mount positions, turns into a kind of tumbling drill.
