EXPRES, THE EXERCISE PRESCRIPTION: THE PERSONALIZED FITNESS PROGRAM OF THE CANADIAN ARMED FORCES. Developed by Participation. Toronto. Macmillan, 1988. 144pp. paper, $6.95, ISBN 0-7715-9545-X. CIP Grades 8 and up Reviewed by Marilyn Aldworth Volume 16 Number 5 1988 September Everyone has heard of the 5 BX and the 10 BX exercise programs of the Canadian Armed Forces. This book claims to be the successor of these programs. Right away that information will either elicit a smile from the self-motivated types or an exasperated expression from those who find this regime a little boring and lacking in inspiration. Charts and tables abound with easy-to-follow training levels. There are no photographs, just basic Illustrations in black and red. Two of my colleagues who are experienced fitness instructors criticized the inclusion of specific exercises that are now considered unsafe—these are side leg raises, reverse push-ups and the lunge (stretching activity). Each program specifies how much activity to do and at what speed or intensity. This is a safe, simple and effective way to train based on a gradual and controlled progression with little risk of injury. Expres is a fitness program that requires little or no equipment. It has something that everyone can use, whether you want to crosscountry ski, swim, jog or do weight-training. It is cheaper than joining a fitness club or buying Jane Fonda's work-out video. Expres provides an abundance of information on becoming and staying fit and on using an exercise program that suits your life-style. Includes a few basic tips on nutrition and injuries. Definitely recommended. Marilyn Aldworth, North Vancouver School District North Vancouver, B.C.
