Good posture is the key to preventing and solving back and hip pain. Bill Gottlieb, America’s #1 natural health coach and author of Bottom Line’s Speed Healing, explains how poor posture can cause pain and also offers specific tips on how to improve your posture. When you sit, keep your feet flat on the floor and sit on a slight slope to help relax your muscles and align your body. Always keep your ears over your shoulders and your chin slightly tucked in. The best posture for sleeping is on your back, but with the proper neck and head support.
