The book is interesting, good advice and easy to follow the instructions. I have been regularly going to the gym since I was 17 years old, now I am 79 and with an estimated age between 71 to 73. The exercises and texts in this book have been in my routine, plus some advice from Reail Age page many years ago.I would recommend its reading for starters and gym participants. It has interesting information on how to evaluate your age in the successive steps on the road to a healthy body and mind.
