Stand up straight with your feet shoulder width apart.
Hold your arms straight out in front of you and take a small step back.
Keeping your abdominal muscles strong and your body straight, lean forwards whilst opening your arms into a "T" position.
Pivot from your toes and ensure you keep a very small bend at both elbows.
Once your arms are directly out to your sides, return to the starting position at a steady speed by pushing through your upper arm and chest muscles.
