Body fat percentage represents the proportion of your total body weight that is fat tissue. The remainder — your lean mass — is muscle, bone, organs and water. A higher lean mass relative to fat is associated with better metabolic health, stronger bones, and greater functional capacity as you age.

Each body region is measured independently. The values shown are segmental soft lean mass — the most reliable indicator of muscle development and balance. Good symmetry between left and right sides reflects consistent training. The trunk reading correlates closely with visceral fat and central health markers.
