While doing your aerobic exercise keep your heart rate between the min and max heart rate, calculated with the formula below, to maximize your fat burning cardio workout.

THE FAT MAX ZONE

1. Calculate estimated maximum heart rate (MHR)
    using the following formula:
          220 minus age = MHR
          Estimated MHR for an average 30 year-old would be:
          220-30 = 190

2. Next, determine resting heart rate (RHR):
          Take your pusle for 1 minute while at TOTAL rest:
          (Typical RHR = 70)
          Subtract RHR from MHR:
          190 - 70 = 120

3. Calculate percentages:
           55% of 120: = 66
           72% of 120: = 86

4. Add RHR (70) back into to both numbers:
           66 + 70 = 136
           86 + 70 = 156

The Fat Max Zone for an average 30-year-old, would between 136 and 156 beats per minute
