STARTING POSITION:
Select the appropriate strength of the band. Stand up straight with the ends of a band in each hand and on either side of your hips. You should use a neutral grip. Put your feet on the band. Contract your pelvic floor and core while keeping your chest up. Maintaining the natural arch of your back, lean forward until your torso is parallel to the floor. You can bend the knees slightly. The arms should be perpendicular to the floor. The band should have tension from the beginning of the movement.
MOVEMENT:
Pull the band up towards your torso retracting your shoulder blades while you exhale until you touch the abdominals. Return to the starting position in a smooth movement.
TIPS: While your are doing the exercise, move only the arms, make sure you don't move any other part of your body. The exercise key is quality over quantity. The trick is to perform the exercise using proper form.
