What Is a Heart Rate Calculator?
A heart rate calculator helps you understand how fast your heart should beat during different activities. Your heart rate changes when you walk, exercise, rest, or push yourself harder. Knowing the right range keeps your workouts safe and effective.
This calculator removes confusion and gives you numbers that make sense for real life.
Why Heart Rate Matters More Than You Think
Many people exercise without knowing if they are pushing too hard or not enough. A heart rate that is too high can lead to fatigue, while a rate that is too low may not give results. Heart rate acts like a guide, helping you stay in the right zone.
How This Heart Rate Calculator Works
The calculator estimates your maximum heart rate based on age. From there, it breaks the number into zones. Each zone serves a different purpose, from light activity to intense training.
You do not need any medical knowledge. The calculator explains everything in simple words.
