BMI (Body Mass Index): A general indicator of healthy weight for your height. However, it doesn't account for muscle mass or body composition.
FFMI (Fat-Free Mass Index): Measures lean muscle mass relative to height. More accurate than BMI for athletes and lifters. Values above 25 suggest exceptional muscularity; above 26 may indicate performance enhancement.
Ideal Weight: Based on the Devine formula, commonly used in medical settings. This is a guideline - your actual ideal weight depends on goals, body composition, and activity level.
