Step 1: Wall Push-Up
Works chest, shoulders, triceps and core.
Place your hands shoulder-width apart on a sturdy wall in front of you, feet slightly apart, abs engaged, back and legs straight. Lift your heels to balance on your toes and lean forward slightly so most of your weight is on your arms. Inhale as you bend your elbows and lean your body farther toward the wall, maintaining a long, straight line from head to toe.
