Primary Muscle Group: Back of upper arms
Muscle Groups Worked in This Exercise: Triceps brachii (lateral and long heads) and that seldom heard of muscle, Anconeus
Preparation: Stand in a lunge position with your left foot forward. Place the band under your right foot and grasp an end in each hand.
Breathing: Inhale as you bend your elbow, and exhale as you return to start position.
Execution: Extend your arms overhead and inhale as you bend your elbows and lower your hands behind your head. Exhale and extend your arms overhead to start position.
Comments: Performing this exercise without the ball stretches the band a little more, creating more resistance.
