Understanding Your Results

Lean Body Mass (LBM) is the total weight of your body minus all the fat. It includes muscles, bones, organs, and water.

Fat Mass is the total weight of the fat in your body.

Body Fat Percentage is the proportion of fat to your total body weight.

Tracking your LBM is important for fitness goals as it helps you understand if you're gaining muscle while losing fat.
