Bun Mut

As mentioned above this move will start slightly differently from the other techniques:

1. Stand with your feet shoulder width apart and parallel to each other facing forward.
2. Bend the knees (the amount you bend is optional).
3. Hold your arms by your sides, bent at the elbows at 90 degrees so that your fore arms are parallel to the ground.
4. Open your hands with your fingers spread.

  The exercise:

1. Straighten your legs and at the same time clench your fists tight.
2. Bend your legs and open your hands hard spreading your fingers.
3. Repeat

After a minute or so, you should feel your fore arms starting to ache, this is a good sign. If you don't feel them aching, then you're not opening and closing your hands hard enough!
