A Clinician’s Guide to Exercise Prescription

Exercise is Medicine(TM) is an American College of Sports Medicine initiative to "make physical activity and exercise a standard part of a disease prevention and treatment medical paradigm." This book will teach practitioners how to motivate and instruct patients on the importance of exercise and how to design practical exercise programs for patients of all ages and fitness levels, as well as those with special conditions such as pregnancy, obesity, and cancer. Coverage includes in-depth discussions of both the lifestyle exercise approach to exercising regularly and the structured exercise approach.
