Max Heart Rate Calculator

By Mateusz Mucha and James Mathison

The max heart rate calculator gives you a target heart rate to aim for while you're training. The speed and distance each of us can and will run varies wildly, depending on our natural ability, training level, sport, and determination. Heart rates, on the other hand, are a more democratic metric, that is only factor that determines it is your age. If your average heart rate while running is in the right zone, you're training well, regardless of your level. Training this way allows you to stay within an optimal yet safe level of exertion, keeping a healthy heart rate while also pushing the limits of your body.

Average heart rate

If you know how fast, on average, your heart is beating during a training session, then you have a great way of determining whether or not you're really pushing yourself. If you cycle hard up a hill in the middle of your routine, but the rest was smooth sailing, you might remember the tough part and forget the rest. Overall, it probably wasn't enough to trigger any real physiological conditioning within your body, even though it doesn't feel like that when you're cycling up that hill.

The only objectively way to know that you are training in a way that will stimulate peak physical conditioning is to record your average heart rate when you train, and then to use a max heart rate calculator to measure your level of exertion. This sort of conditioning is essential for any endurance sport, and it's also useful for any sport that pushes you to physical extremes. A training regime like this will make sure you leave your opponents in the dust!

Healthy heart rate

Be sure not to push yourself too close to your maximum heart rate for extended periods of time. If you experience shortness of breath, pain in your chest or joints, or can't work out for as long as you expect, you might need to reduce your training intensity. Safety should be your first priority in training, and that includes maintaining a healthy heart rate. It doesn't matter how hard you train, if you injure yourself before an event!

Heart rate training

When training for an event, you should know the different ranges of heart rates, and what they mean.

  • The recovery zone - 60% to 70%
  • The aerobic zone - 70% to 80%
  • The anaerobic zone - 80% to 90%
  • The red line zone - 90% to 100%

Training in the recovery zone builds a basic foundation of endurance and aerobic capacity. The aerobic zone beefs up your cardiovascular system. In the anaerobic zone you'll hit your "anaerobic threshold", at which point you'll switch on lactic acid system. You'll start to feel the burn! Lastly, training in the red line zone can only be done for short periods, and develops your fast-twitch muscle fibers. By keeping your average heart rate in this zone you'll build your capacity for short-lived yet explosive power and speed. This is where sprinters train.

Follow these steps to train optimally next time you're on the track or at the gym:

  1. Use the target heart rate calculator to know what heart rate you need to put you in the zone you want.
  2. Train with your heart beat monitor and record your average heart rate.
  3. Open your max heart rate calculator.
  4. Punch in your age.
  5. See if you trained in the correct range, and what it means.

You might also find the pace calculator useful, which tells you how much time you need to run a particular distance. People who use the max heart rate calculator often also use our bench press calculator, which gives you your one rep maximum. Just like your max heart rate, your one rep max gives you a benchmark which helps you train optimally.
