Apart from being able to relax under a choke it can also be used to help you become aware of your body and when one system is in nead the rest line up to form the best energy savings alignement for you. Consider this: Stand naturally and start to sway from side to side and breath count with the sways. Start with 2 for each phase Inhale pause Exhale pause. Now sway forward and backwards and also diagonally (left heel to right toe axis) Once 2 is easy raise the count and see how you relax and align the body under this condition you put yourself in. It is the purpose that matters. A push up is a push up. The meaning makes it different. Oh and don’t rise too fast. Be logical.
