Tie the resistance band around your lower thighs, just above your knees, moderately snugly. Lie on your side with your knees bent, one leg on top of the other. Keeping your feet together, lift your top knee as far as you can without rotating backwards, feeling the resistance of the band. Slowly and in a controlled manner, lower your leg back to the original position. Repeat 20-25 times, then do the same with the other leg.
