What is Lean Body Mass?

Lean Body Mass (LBM) is the total weight of your body minus all the fat mass. It includes the weight of your organs, skin, bones, and muscles. LBM is a more accurate indicator of body composition and health than total body weight alone, especially for athletes or those with high muscle mass.
