Frequently Asked Questions
Your BMI classification indicates whether your weight is healthy for your height. Classifications include Underweight (<18.5), Normal Weight (18.5–24.9), Overweight (25–29.9), and Obesity (30+).
BMI is a general guideline but may not account for factors like muscle mass or body composition. Athletes with high muscle mass may have higher BMIs despite being healthy.
Checking your BMI periodically can help track changes in your weight and overall health. Monthly or quarterly checks are sufficient for most people.
