How to use these tools
Start with the BMI calculator for a quick screening number, then use the BMR calculator and daily calorie estimator to understand your energy needs. If you are training, the heart-rate zone calculator helps you pace sessions in a cramped ship’s gym or on deck.
Before a medical examination, the blood pressure reading guide and the medical preparation checker help you arrive prepared.
