Are you working within your target heart rate zone? Your target heart rate zone (training zone) is the range between 60% and 80% of your maximum heart rate. Working within this zone gives you the maximum health and fat-burning benefits from your cardiovascular activity.

To determine if you're working within your zone, locate your radial artery at the side of your wrist with your index finger, and count the beats for 10 seconds, then multiply by 6. This result should be within the minimum and maximum training heart rate values listed below.

For  individuals who are sedentary or have been exercising regularly for less than 6 months, use the Beginners/Intermediates calculator.   Advanced Exercisers  --   those who have been exercising regularly for at least 6 months. -- can use the Advanced calculator.

To use the calculators, simply enter your age (and resting heart rate for Advanced Exercisers), then click the Calculate button to see your results.  (Please note that your browser must be Java Script enabled to use the calculators)
