STARTING POSITION:
Suspend your TRX at around knee height. Lie flat on your back with your heels on the handles of the TRX. Your legs should be straight. Place your hands on either side of your hips. Contract your pelvic floor and core
MOVEMENT:
Through with your heels, slightly extend your hips vertically. Fully bend your knees moving your heels towards the butt. Exhale during the movement. Return to the starting position with a smooth movement while you inhale.
TIPS: The exercise key is quality over quantity. The trick is to perform the exercise using proper form.
