EXERCISE 29.
Extend both hands in front of you, palms together, the fingers of each hand held tightly against those of the other, the thumbs separated from the others and pointed toward you.
Raise the elbows from the body, then slowly and with muscular resistance move the palms apart, keeping only the tips of the fingers together. Push hard with the finger tips against each other. Just as slowly and with muscle resistance close the palms again. Repeat this exercise five times.
