Primary Muscle Group: Backs of upper arms
Muscle Groups Worked in This Exercise: Triceps brachii; medial, lateral and long heads, as well as a little mentioned muscle, the Anconeus
Preparation: Your resistance band should be attached to a sturdy object of a suitable height so that it is as far as possible above your head height. You should be standing with feet hip-width apart and your abs should be nice and tight. Grasp the handles with an overhand grip and lock your elbows by your sides. Bend your arms until your hands are at shoulder height.
Breathing: Breathe out as you straighten your arms; breathe in when you return to start position.
Execution: Now, slowly extend your arms and push the handles down until they are touching your thighs. Slowly, bend your arms back to the start position.
Comments: Your upper arms and elbows should be fixed right at your sides; be conscious of them trying to swing out as you lift up. Also, your shoulders and back should remain still throughout the range of motion for the greatest benefit.
