اکثر پوچھے جانے والے سوالات
What is lean body mass?
Everything except fat: muscle, bone, water, organs. More useful than total weight for athletic performance.
Why is LBM important?
Determines calories for maintenance, strength capacity, metabolic rate. Athletes focus on LBM, not total weight.
Can LBM increase without weight gain?
Yes—if muscle increases and fat decreases (same weight). Requires resistance training and good nutrition.
