Heart Health Calculators

Why keep an eye on your heart health numbers?

Your heart rate and blood pressure are two of the simplest, most useful signals your body gives you — and both are easy to check regularly without any special equipment beyond what most people already have at home.

Which calculator should you use?

• Heart Rate Zones — find your target training zones (light, moderate, hard, max) based on your age and resting heart rate, so you can train with purpose instead of guessing.
• Blood Pressure Checker — see where a reading falls on the standard chart (normal, elevated, high) and understand what the numbers actually mean.

A note on accuracy

These tools are educational estimates, not a diagnosis. Blood pressure in particular can vary through the day and is best tracked over multiple readings — if a result looks unusual or you have ongoing concerns, talk to a doctor.
