Question: what is the formula used to calculate lean body mass?
Answer: Calculate your LBM using your height and weight. Men: Lean body mass = (0.32810 × W) + (0.33929 × H) − 29.5336. For women: Lean body mass = (0.29569 × W) + (0.41813 × H) − 43.2933. Note: 1lb = 0.453592kg, and 1in = 2.54cm. You can also go the easy route and use an online calculator like this one here.
