Good posture

Pegram also demonstrates what bad posture looks like.

To help your posture, plank exercises can strengthen your core muscles. A proper plank position looks like a push-up, except your elbows are bent at 90 degrees and you’re resting your weight on your forearms. Your elbows should be right below your shoulders and your body should be in a straight line from your head to your feet.

If resting your weight on your forearms is too difficult or painful, start with your arms straight instead. Try to hold a plank position for at least 10 seconds, working up over time to a goal of one minute.

Core exercises to enhance posture can include arm and leg motion too, such as this quadruped.
