A. Stand two arm’s-lengths apart from each other, back against a wall, arms near your sides and heels about six inches (15 centimetres) from the wall. Your bum, shoulders and the back of your head should be touching the wall.

B. Draw your abs toward the wall as you also flatten your lower back against it. With head and shoulders still touching the wall and abs tight, slide your arms up the wall, bending your elbows to 90 degrees. Your upper arms should be in line with your shoulders, and your lower back should remain flat against the wall.

C. Relax your shoulders. Hold this position for 30 seconds, then move on to the next exercise.
