STARTING POSITION:
Select the appropriate strength of the band. Tie the band to something stable in front of your and sit on a chair. Grab the band with a neutral grip. Make sure your torso is at a 90º from your legs. Contract your pelvic floor and core while keeping your chest up. The band should have tension from the beginning of the movement.
MOVEMENT:
Pull the band back towards your torso retracting your shoulder blades while you exhale until you touch the ribs. Return to the starting position in a smooth movement.
TIPS: Make sure your torso doesn't move in any moment.
