What you’re working: Pectorals, deltoids, triceps and traps, while core keeps you stable with correct form.
How to do it: This is a modified pushup, but you can’t cheat and use your knees! Try it on the floor first, starting in plank position and lowering yourself down. Be sure to keep the lower body in alignment with upper body, being careful not to arch your back either way. Lower your body to about fist height off floor and then push yourself back up to plank position. Quality over quantity is the name of this game. Continue for one minute.
Tip: For a modification, do an elevated push up using either a chair, bed, bench, bar or other object that will hold your weight and not cause you to fall. Use the same form you would use on the floor, maintaining that good body position.
