BMI Calculator

Check your Body Mass Index (BMI).

BMI calculator - quick body mass index check

The BMI calculator computes body mass index from your weight and height. It provides a fast, high-level screening metric for body-weight status.

For endurance athletes, BMI is useful as one reference point, not a complete assessment. It should be interpreted alongside body composition, training load, and performance trends.

Track BMI over time to monitor direction rather than single-day changes. Better decisions come from combining multiple health and training indicators.
