COULD YOU DO THIS AT 18 MONTHS?

Could you climb a smooth slide as the baby on the front cover does when you were a year and a half old?

Of course not. But perhaps you could have, had you been given the training that 18-month-old Johnny, pictured in one of his favorite exercises, has gone through; for his twin brother, Jimmy, who has lived the untrained life of a normal infant, cannot climb and skate and swim and dive like his brother.
