The 2 Ways (Formulas) to Calculate Target Heart Rates for Safety, Health, and Fitness

For the best fat burning results, cardiovascular target heart rates should be used. To determine a target heart rate for an apparently healthy person with controlled risk factors and not using any medication that affects heart rate and dynamics will use age predicted maximum heart rate or APMHR to determine the best cardiovascular target zone. APMHR is two hundred twenty minus ages. Sixty to eighty percent of this uses the aerobic energy system burning fatty-acids and carbohydrates. At eighty to ninety percent, the subject is burning a combination of protein and carbohydrates.
