The goal of this assignment is to become familiar with online body composition estimations, as well as field tests that are available at health and wellness centers, health clubs, or even a local gym. It is important to know the difference between an estimate and a direct measurement, as well as the reason one would use either to assess lean muscle tissue and body fat percentage. The latter portion of this assignment might take some planning and a small financial investment on your part, depending on what option you select for the body composition test. The information gleaned from this test is invaluable and will deepen your understanding of how to determine body composition and make improvements upon a baseline value.
