Good posture, like that of a young child, shows a natural S-curve and effortless movement. Poor habits like slouching and inactivity cause muscle tension and fatigue, leading to back pain, joint issues, rounded shoulders, and a potbelly. Improving posture and spinal health is possible with simple lifestyle changes. For guidance, consult your doctor, physiotherapist, chiropractor, or an Alexander technique teacher to get personalized advice and support.
