Starting Position: Lie flat on your back on the floor / mat adjacent to a wall edge (corner) or in a door jam.  Elevate one leg to rest against the wall while the other leg will lie flat on the floor / mat past the wall edge or door jam.  Adjust your position to allow you to rest as much of the back of the elevated leg against the wall without having to lift your hips off the floor and point your toes towards the ceiling.  Extend your arms outwards at shoulder level with palms facing upwards and stiffen (“brace”) your abdominal muscles to stabilize your spine.
