This is a general guideline and this is some variation in this, so don't be concerned if you are exercising with a heart rate monitor and notice your max heart rate varies slightly to the calculation. This does not burn the most kilojoules, and may not be the most effect method for weight loss, but that is a different debate.

If you are exercising hard, your muscles are producing a lot of energy and have a high energy demand. You may want to exercise at 50-70 of 200, and 70 of your max heart rate may be the way to go.

This makes sense. Exercise over 85 cannot be sustained for very long. Using the 20 year old example again, with a max heart rate of 200bpm.Heart rate monitors are a great way to monitor the intensity of an exercise session. Heart Rate Zones Now that you know your max heart rate you can calculate at what intensity you would like to work at.

So if you want to go for a long steady state run, your best bet is to program your heart rate for a zone lower than 85 is a good aerobic training zone. Generally the higher your heart rate is, the harder you are working. In order to get oxygen to the working muscles to help in the production of energy, the heart must pump harder and faster. So if you are 20 years old, (220-20), your max heart rate should be around 200 beats per minute. The calculation is a guideline and not a hard and generator motor Suppliers fast rule. More blood circulates, transporting more oxygen to cells. This zone can be set on your heart rate monitor.
