Calculate your precise Lean Body Mass (LBM) to monitor pure muscle changes and optimize your gym goals.
Your Lean Body Mass represents everything in your body—muscle, bone, organs, and water—excluding fat tissue. Tracking your LBM ensures that when you lose weight, you are burning actual fat rather than accidentally wasting away your hard-earned muscle mass.
Input your gender, age, height, and current weight. The calculator runs the clinically validated Boer formula to output your exact lean tissue weight and absolute body fat weight.
