This move seems simple, but doing it right helps with posture and balance. Stand with your big toes touching, heels slightly apart (or wider if that’s more comfortable), arms by your sides. Imagine lifting through your inner feet and ankles. Pull your shoulder blades down, and widen your collarbones. Keep your head in line with your shoulders (not pulled back or forward), your chin parallel to the floor. Your pelvis and lower back should be neutral, not tucked or arched. Hold for 30 seconds to 1 minute.
