STARTING POSITION:
Select the appropriate strength of the band. Stand straight with your feet shoulder width apart. Put the band around a ladder at your belly height. Grab the band with a neutral grip and step back to put tension on it. Contract your pelvic floor and core while keeping your chest up.
MOVEMENT:
Retracting your shoulder blade, pull the band toward the ribs with your right hand. Exhale during the movement. Return to the starting position with a smooth movement and repeat with the other arm. Everytime that you do the exercise, you should rotate your trunk in the same direction of the pull.
TIPS: The exercise key is quality over quantity. The trick is to perform the exercise using proper form.
