What I should practice:
Anything resembling a ball-up. Any stretch/flexion that helps me ball up tighter and/or pull knees closer into chest. Examples: seated rolls onto rounded back, into candlestick position, rocking pistol without worrying about standing up out of it.
Balancing on a hand and foot while extending middle arm in front and counterbalancing with middle foot in back, ie, balance on right hand and left foot while reaching forward with left arm and backward with right leg. Do this on a balance board/beam. Breathe in the belly and relax to balance. Pick something up off the floor with the extended hand.
Heavy 1-hand farmer walk on balance board.
Shoulder rolls with “diamond hands.”
There’s more. I need to write it down sooner tomorrow after my session.
