Stand with your left shoulder (and left side of your body) against the wall (your abdomum (sic) is at right angles to the wall)
Lift your left leg off the floor by bending it back at the knee. You're now standing on your right leg only propped against the wall
Bend your left leg at the knee, your now in a propped up running pose.
Push your left hip against the wall and take the reaction of this force on your right leg,
Two minutes later, grit your teeth....and three minutes later wipe the tears from your eyes
Repeat facing in the other direction.....teeth gritting and tear wiping will still apply.
