There are many ways to stretch your adductors (inside thigh) and the various muscles around the hip – here’s one way that ensures your legs are turned out during the stretch.
13Lie on your back with your legs against a wall, rotate the legs outwards then drop down sideways. Rest your hands on your inside thighs but don’t pull the legs. Now flex your feet to increase the stretch and aim to bring your toes towards the floor.  Keep your back pressed into the floor. 30-60 seconds maximum per stretch. Never stretch through pain.  Relax and breathe!
