How to do it: Stand up straight in front of a wall and place your palms against it, wider than shoulder-width apart. Step back until your arms are extended, but don't lock your elbows [A]. Keeping your body straight, bend at your elbows until your nose nearly touches the wall [B]. Push through your palms to return to the starting position.
Tip: Keep your body in a straight line as you perform the move. The closer you stand to the wall, the easier this exercise will become.
