Upper arms. Using the edge of a chair, pin your elbows into the back of your waist so they’re pointing behind you. Step your feet away from the chair while keeping your hips back to the chair. Lifting up and out from the top of your shoulders, bend your arms as you lower your body, trying to skim the side of the chair. For extra burn, hold the last rep and go into medium-range pulses. For advanced, do this move with straight legs.
20 reps, then 10-20 pulses.
