Muscle Mass Estimator

What is Muscle Mass?

Muscle mass refers to the total amount of skeletal muscle in the body. It plays a key role in physical strength, metabolic health, and mobility. Estimating muscle mass is important for fitness goals, health monitoring, and detecting conditions like sarcopenia (age-related muscle loss).

Why is Estimating Muscle Mass Important?

Knowing your muscle mass helps track progress in strength training, assess overall health, and optimize weight loss or weight gain strategies. It can also identify imbalances in body composition that may impact physical performance or increase health risks.

How is Muscle Mass Estimated?

The Muscle Mass Estimator uses the following parameters to calculate muscle mass:

• Gender: Muscle mass is typically higher in males than females due to differences in body composition.
• Body Fat Percentage (Optional): A lower body fat percentage indicates a greater lean body mass, which includes muscle.
• Height and Weight: These measurements provide context for estimating body composition and proportions.

When body fat percentage is provided, the calculation determines lean body mass (LBM) and estimates muscle mass using gender-specific factors:

Lean Body Mass (LBM) = Weight × (1 - Body Fat % / 100)
Muscle Mass = LBM × Gender Factor

Where Gender Factor is 0.50 for males and 0.40 for females.

Example Calculation

Inputs:
  Gender: Male
  Age: 24
  Height: 170 cm
  Weight: 65 kg
  Body Fat Percentage: 15%

Calculation:
  Lean Body Mass = 65 × (1 - 15 / 100) = 55.25 kg
  Muscle Mass = 55.25 × 0.50 = 27.63 kg

Result:
  Estimated Muscle Mass = 27.63 kg
