Stand holding the resistance band with one arm above your head.
Take a step forward on the opposite leg as the arm holding the band, and lift your other leg back behind you.
Twist your body forward and rotate to bring the band down to touch your knee on your stance leg.
Ensure your body remains straight.
Your elevated leg should rise up behind you as your body tilts forward.
Make sure the movement is smooth and you use the strength in your abdominal muscles to control the rotation.
