MUSCLES ENGAGED Triceps Triceps are an often forgotten muscle group. Triceps are located on the opposite side of the biceps at the back of the upper arm. Well strengthened and defined triceps make the arm look bigger and sleeker (reducing the "flabby arm" look). Equipment Used Resistance Band n/a Exercise Instructions Step 1 Start with your feet hip width apart and lean forward slightly while holding the exercise band in each hand. Step 2 Tuck your elbows into your side and keep your shoulders down and back flat as you fully extend your elbows. Step 3 Squeeze your triceps at the the bottom of the extension and return back to the starting position with full control.
