Why Lean Body Mass is the Real Metric for Success
Most beginners focus on total body weight, but elite athletes track Lean Body Mass (LBM). LBM is the most accurate predictor of your Basal Metabolic Rate (BMR). The higher your LBM, the more calories your body requires just to stay alive.
Calculating Your Metabolic Engine
Every pound of muscle you gain through Resistance Training increases your metabolic flexibility. By tracking LBM alongside Body Fat Percentage, you can ensure that the weight you lose during a cut is actually fat, not muscle.
Formulas used
This calculator uses the Boer Formula, which is widely considered accurate for most body types.
