Place the hand on a flat surface with the fingers curved so that just
the tips and the base of the palm touch the table. Raise and lower the
fingers one after the other slowly and with muscular resistance. Bring
the fingers down with considerable pressure each time. Repeat twenty
times with each hand.
With the fingers in the same position raise the thumb as high as
possible, and bring it down sharply to the table. Repeat twenty times
with each thumb.
