Lie on your back and place a towel or stretching strap around the foot of your affected leg.
Keep your leg straight and pull on the strap, moving the leg up until you feel a stretch down the back of the leg.
Next, let your leg gently fall out to the side towards the floor until you feel a stretch in your inner thigh.
Keep your hips and shoulders flat on the floor throughout this movement.
Hold this position before you bring the leg back to the starting position.
