Body Composition is defined in physical fitness as the percentage of fat, muscle, and bone in the body.
Usually it is expressed as a ratio of lean mass to fatty mass. Lean mass includes muscle, bone, skin, internal organs and body water. Fatty mass is mostly composed of body fat (subcutaneous fat) as well as internal essential fat surrounding organs. Body composition will typically be displayed as either a percentage of fat (body fat percentage or "% fat") or as a percentage of lean body mass (LBM).
