Band shoulder extension strengthens the muscles that pull the arm backward, working against a resistance band. You stand facing the anchor with the elbow bent and the hand in front of you, drive the elbow straight back until it is a little behind your body, then let it return slowly. The main movers are the broad muscle along the side of your back (latissimus dorsi) and the back of the shoulder, and it is a common step up from moving the arm back with no resistance.

How to do the band shoulder extension

Fix one end of a resistance band to something sturdy in front of you at about waist height, and hold the other end in the hand of the arm you are working.
Face the anchor, standing upright. Bend the elbow to about a right angle, with the forearm pointing forward and the hand at waist height, and move back until the band just starts to pull.
Keeping the elbow bent and close to your side, pull it straight back until it passes behind your body. The voice guide puts the end point at about 45 degrees behind your back.
Hold briefly at the back, with your chest still and the shoulder low, away from your ear.
Let the elbow travel forward slowly to the start, keeping control of the band, and repeat.

What you should feel

Work at the back of the shoulder and down the side of your back toward the armpit, with some effort between the shoulder blades.

Common mistakes

Leaning back or twisting the trunk to finish the pull.
Letting the shoulder roll forward as the elbow goes back.
Pulling with the hand and bending the wrist instead of driving the elbow back.
Rushing the return so the band snaps the arm forward.

How often

Many programs use 2 to 3 sets of 10 to 15 slow pulls with a light band, once a day or a few days a week. Your physio will adjust this.

Stop and check with your physio if

A sharp pain or pinch at the front of the shoulder as the elbow goes back.
Pain, pins and needles or numbness spreading down your arm or into your hand.
Pins and needles in your arm or hand that do not go away after you stop, or part of your arm or hand goes numb. Get medical advice the same day. If one side of your face or body suddenly goes numb or weak, or your speech becomes slurred or muddled, call emergency services, even if it goes away.
A sudden pop or tearing feeling in the shoulder that brings sharp pain, new weakness or trouble lifting the arm. Stop and contact your surgical team the same day, or get medical advice the same day if you have not had surgery.
The shoulder feels as if it has slipped out of place, looks a different shape or suddenly locks so you cannot move the arm, or your hand turns cold, pale or blue. Go to an emergency department straight away, without driving yourself, and do not try to put the shoulder back in yourself.

From the clinic

It looks a lot like a one-arm resistance band row. The aim is different. Here the elbow travels past your side to take the shoulder backward, while the row finishes with a squeeze of the shoulder blades. Stop the elbow while the front of the shoulder still feels comfortable. The last part of the range stretches the front of the joint.

Choose an anchor that cannot move, such as a heavy table leg or a firmly shut door, and check the band for nicks before you start. If you have high blood pressure, breathe steadily through every repetition and never hold your breath.

After shoulder surgery, including a rotator cuff repair, or after a shoulder fracture or dislocation, follow your surgeon's or physio's plan, and do only the movements and range they have cleared. Many plans allow only passive movement at first, where the arm is moved for you and its muscles stay relaxed. Taking the arm back behind your body, and pulling against a band, are both usually held back in the early weeks after some shoulder operations, so ask when this can start.

If a band is too much for now, isometric shoulder extension works these muscles with the arm pressing into a wall. The straight-arm band pulldown trains the same backward pull with the elbow kept straight.
