Where:

• \( BMI \) — Body Mass Index (unitless)
• \( age \) — Age in years
• \( sex \) — 1 for male, 0 for female

Explanation: The equation accounts for the relationship between BMI, age, sex, and body fat percentage, with adjustments for muscle mass in weight lifters.

3. Importance of Body Fat Calculation
