Well, maybe Joan wouldn't be mad if I just read a couple of sentences. What could it hurt. I mean there you are exhaling as you release the doorknob.

Actually I think you're supposed to exhale as you turn the doorknob and then inhale as you release the doorknob.. Remember – as you exert force, you exhale. When you return to the resting mode which would be releasing the doorknob you inhale giving your body more oxygen. Exhale as you twist, inhale as you release. I'm really not supposed to go beyond this first sentence so I thought I did everything I could with that.
