In this book, readers learn about physical fitness in an entirely new way, through graphs! This book contains 28 graphs of common physical fitness activities, including: Aerobic Exercise, Exercise Equipment, and Weightlifting. Graphs contain a selection of physics data including acceleration, velocity, trajectory, and force, as well as biophysics data such as breathing, joint angle motion/positions, blood pressure and heart rate, and the electrical activity of the heart (EKG) and muscles (EMG).
