Decline Push Up
Step by step guide:
Place your feet on an elevated surface such as a ledge, a step, a chair, or a stack of books.
Place your hands slightly outside shoulder width and straighten your body to hold a tall plank position.
Lower yourself down until your body drops below your elbows, the push yourself back up.
Common mistakes:
Letting your body sag down towards the ground. The purpose of this exercise is to target the muscles of the upper chest and shoulders, and sagging your body down negates this. Make sure you’re maintaining a straight line between your heels and shoulders.
Not going low enough. Force yourself to drop your torso below your elbows. Make sure you master regular push-ups before doing these.
