Start lying on your back with your foot in an exercise band, leg straight and lifted up to 90 degrees.
Find pelvic neutral, engage pelvic floor and deep transverse abdominals. Engage gluteus medius and maximus by turning out slightly at the hip (to find hip neutral) and engage VMO by straightening your knee fully. Then move your leg away from your body midline until you feel a stretch in your inner thigh. Keep knee straight.
