Straighten out Stand with your back pressed against the wall and place your feet 30cm apart and 10cm away from the wall. Sink down Slowly bend your knee(s) and slide down the wall by 45cm, making sure your-middle back is touching the wall. Push back up Return to the start; keep your lower back on the wall as long as possible. Walk away with your head held high. And it can be as simple as lying on the floor with your knee(s) bent, using two or three books as a headrest (staying in this position for 10 minutes can rid you of shoulder cramps,) or rolling your head(s) forward to improve your posture. Inch your way to success.
