When out shoveling (see photos from tonight here), use these Anusara alignment principles as a mantra to keep yourself doing them: shins in, thighs out, tailbone tucked, upper arm bones integrated into the shoulder socket, shoulder blades hugged to the back of the heart. Oh yes, arm bones integrated, shoulder blades onto the back of the heart.
Afterwards, try a few slow sun salute variations to reintegrate and align. Follow with vipariti karani (legs up the wall), supported supta baddha konasana (supported reclining bound angle pose, and a few hip openers of choice.
