STARTING POSITION:
Select the appropriate resistance in the weight stack. There should be a handle that is attached to a low pulley at your waist height. Grab it with both hands. Stand up straight with your left shoulder pointing to the pulley. Contract your pelvic floor and core while keeping your chest up.
MOVEMENT:
Using your arms and oblique muscles, pull the handle and rotate your torso while you exhale. Return to the starting position in a smooth movement while you inhale. Repeat the movement for the specified amount of repetitions and then repeat with the other side.
TIPS: The exercise key is quality over quantity. The trick is to perform the exercise using proper form.
