Smarter Workouts: The Science of Exercise Made Simple was written to help you understand how exercise changes your body and the most effective exercise solutions to help enhance your quality of life. Chapter 1 of Smarter Workouts is titled, "How Exercise Changes Your Body" and organizes exercise into three main categories: force production (which includes the entire spectrum of endurance, strength and power), mobility and metabolic conditioning. Muscles control physical force in your body; when a muscle contracts it produce a force to move an object, when a load is heavier than a muscle can control, it responds to that external force by lengthening. In the first part of How Exercise Changes Your Body, you will start learning about how your muscles work and the most effective ways to use exercise to make them more efficient at generating force. Tip: form follows function; helping your muscles to perform more effectively is the first step towards helping them look their best.
