"Leg motions next," Eric called briskly. "At the word 'One!' bring the body down to the heels in a sitting position. At the word 'Two' straighten up and jump with both legs wide apart. At the word 'Three,' jump and bring the legs close together. That's the one that shoots you ahead."

This was repeated a dozen or more times and then Eric started the youngsters doing both the arm and leg motions together. It was really hard work, but when he let the urchins go at the end of about half an hour, some of them could do it like clockwork.
