A common formula for determining maximum heart rate consists of subtracting your age in years from 220, explains WebMD. Another possibly more accurate formula multiplies the age by 0.7, and then subtracts that figure from 208.

The intensity and duration of a workout determines the amount of calories burned, notes WebMD.

You burn more calories at a higher intensity, but it's easier and safer to maintain a lower intensity workout for a longer period of time.Learn more about Exercise
