This book presents data on the motions involved in using common exercise equipment, including free weights and stationary bicycles. Graphs show the body in motion over time, focusing on relevant joints. Graphs show the x-y positions of the hip, knee, ankle, shoulder, elbow, and/or wrist during exercises. These data can be used for lesson plans by teachers and parents. Note: These biophysics data are samples from one individual and are not representative of the population.
