Lean Body Mass (LBM) is the weight of your body minus all the weight due to fat. For bodybuilders and strength athletes, LBM is crucial for determining optimal nutrition and training strategies. This calculator uses the Boer Formula, which is known for its accuracy across a wide range of body types.

Applications of Lean Body Mass for Bodybuilders

  1. Protein Intake: Many bodybuilders aim for 1.6-2.2g of protein per kg of LBM.
  2. Calorie Calculations: LBM is used to estimate Basal Metabolic Rate more accurately than total body weight.
  3. Tracking Progress: Monitoring LBM helps distinguish between muscle gain and fat loss.
  4. Supplement Dosing: Some supplements, like creatine, are often dosed based on LBM.
  5. Strength Potential: LBM correlates with potential strength gains in weightlifting.
