STARTING POSITION:
Select the appropriate strength of the band. Stand up straight. Grab the band with both hands using a supine grip. Bend your elbows around 90º. Contract your pelvic floor and core.
MOVEMENT:
Rotating your shoulders, tense the band as much as you can while you do a retraction of your shoulder blades. Keep the elbows close to the body. Return to the starting position in a smooth movement while you inhale.
TIPS: While your are doing the exercise, move only the shoulder joint, make sure you don't move any other part of your body. You can hold a towel between your elbows and torso to perform the exercise correctly.
