Re: Breathing Practices
I use conscious breathing techniques, FWIW in:
Yoga -- breathe "into" a joint, muscle or area of the body, use the rhythm of breath to deepen the posture/relax. Some Venassa.
Cardio -- vary breathing rate, depth, rhythm to maximize oxygen flow; vary the "shape" of the breath depending on the kind of sport and how it positions/contorts the body (e.g., cycling as opposed to swimming).
Meditation -- what I'd call "belly breathing," to calm and focus my mind.
Recently, in practice, what I think of as "reverse breathing" during certain techniques (e.g., suwari waza kokyu ho).
Parenting. Just breathe.
