Stand up straight with a resistance band fixed securely under your foot on the same side as the shoulder to be exercised.
The rest of the length of band should run vertically up behind you, held firmly on the top of your shoulder with your opposite hand.
With some tension in the band, ensure you are stood up straight looking directly ahead.
Shrug your shoulder up towards your ear against the resistance of the band.
Imagine your shoulder blade pulling tightly against your rib cage.
Control the movement as you lower your shoulder back down and then repeat.
