Max Heart Rate
A precise tool.
What is the Max Heart Rate & How does it work?
The maximum heart rate (MHR) represents the highest number of beats per minute your heart can safely achieve during intense physical activity.
It is commonly estimated using the simple age‑based equation, which provides a quick baseline for designing cardio workouts.
MHR = 220 – \\text{age}
age = your age in years
Knowing your MHR helps you calculate target zones (e.g., 60‑80% of MHR) to improve endurance, burn fat, or boost performance safely.
