What is Lean Body Mass (LBM)?
Lean Body Mass (LBM) is a part of your body composition that represents the weight of your muscles, bones, ligaments, tendons, and internal organs. Simply put, it is your total body weight minus your total body fat weight.
Knowing your LBM is crucial for athletes, bodybuilders, and anyone trying to lose weight safely. When losing weight, the goal should always be to lose fat while preserving as much Lean Body Mass as possible.
