1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared. While BMI is a useful screening tool, it has limitations for gym-goers with high muscle mass.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in meters

Explanation: The formula divides your weight by the square of your height to give an estimate of body fatness.

3. Importance of BMI for Gym-Goers

Details: While BMI is a useful general health indicator, athletes and gym-goers should interpret results with caution as muscle weighs more than fat. A muscular individual may have a high BMI without excess body fat.

4. Using the Calculator

Tips: Enter your weight in kilograms and height in meters. For best accuracy, measure weight in the morning before eating and after using the bathroom.

5. Frequently Asked Questions (FAQ)

Q1: Why might BMI be inaccurate for gym-goers?
A: BMI doesn't distinguish between muscle and fat. Very muscular people may be classified as overweight or obese despite having low body fat.

Q2: What are normal BMI values?
A: Underweight: <18.5, Normal: 18.5-24.9, Overweight: 25-29.9, Obese: ≥30. Athletes may fall into overweight category without health risks.

Q3: What are better alternatives for gym-goers?
A: Body fat percentage measurements (via calipers, DEXA scan, or bioelectrical impedance) provide better insight for muscular individuals.

Q4: Should I worry if my BMI is high but I'm muscular?
A: Not necessarily. Consult with a fitness professional to assess your body composition through other methods.

Q5: How often should I check my BMI?
A: For most people, monthly checks are sufficient to track progress. More frequent measurements may show normal fluctuations.
