Why Lean Body Mass Matters
Lean body mass includes muscle, bone, organs, and water. Tracking lean mass helps you understand body composition changes beyond scale weight.
If you know your body fat percentage, the estimate becomes more precise. Otherwise, we use standard formulas based on height and weight.
