Practice standing well at the supermarket checkout, while waiting for a bus, or at the water cooler. Stand with feet hip-width apart, outside edges parallel. Shift your bodyweight so it is equal between both feet: sway from side to side and forward and back to test your balance. Center your hips over your knees. Draw your abdominal muscles back and bring your buttocks together without gripping. Extend from hips to armpits equally on both sides. Broaden your chest, relax your shoulders, keeping them centered over your hips, and lift through the back of the neck.
