When I introduced Aerobics as a new concept of exercise,

my chief aim was to counterac.t the problems of lethargy

and inactivity which are so prevalent in America. There-

fore, my first book was mainly a motivational book, but

also it was an attempt to encourage people to examine

more closely the benefits to be gained from regular exer-

cise. The wide public acceptance of AEROBICS indicates

that these objectives have been at least partially achieved.

The present volume serves a different purpose. As a

result of the comments from people in all walks of life

and the accumulation of vast amounts of new data, it has

been possible to prepare a book which discusses in great

detail the specific requirements for safely and effectively

entering an age-adjusted exercise program. For this reason

I hope that the faithful follower of AEROBICS as well as

the unconditioned beginner will find this sequel to AERO-

BICS both interesting and challenging. Because of the

expanded range of exercise options, the adjustment for

age, and the comprehensive data tables, I also hope that

physical educators and medical personnel concerned with

exercise will find this book useful in supervising physical

conditioning programs. I think of this book as an Aerobics

handbook or Aerobics guidelines.

Whether this book is used as an individual exercise

guide or as a professional reference work, it is my pro-

found hope as a physician that it will serve its readers as

a key to health and well-being.
