Posture is how you hold your body when you sit, stand, and move. Body mechanics is the way you use your body safely during daily activities. These include things like lifting, bending, carrying, and reaching. Good posture and safe body mechanics help protect your spine, hips, pelvis, and the muscles that support them.
Practicing good posture and body mechanics is important at any time in life. But it is especially important during pregnancy. Your body is changing quickly, and your joints and muscles are under more stress than usual.
