The Strength-Training Workout for Better Posture

Many workouts fail to target the obliques or the gluteus medius (a smaller muscle in the group of three muscles that form your butt), says Neuharth. Planks are a total-body exercise, but side planks specifically can help hit these two muscles and improve posture by creating more stability in your low back and pelvis.

Try this exercise: Lie on your side, elbow directly under your shoulder. Engage lower abdominal muscles before lifting hips into the air, as you try to create a straight line from head to toes. If you need to modify, you can start on your knees. Hold for 15 to 30 seconds maintaining proper form, and work your way up to a total of 2 minutes on each side.
