EXERCISE 15.

[Illustration]

Hold your left arm across the chest palm up, but with the wrist bent as

far down as possible, the fingers easily curled. Place the right arm in

a similar position, but with the palm down, having the wrist of the

right hand bent upward and fingers similarly curled. Lay the finger tips

of the right hand on those of the left. From this position twist the

forearms in opposite directions until the finger tips again come

together, this time the palm of the right hand bent up, and of the left

bent down.

Reverse the motion and repeat the exercise twelve times.
