Cardio-Respiratory Fitness

A simple way to determine your maximum heart rate is to use the following formula: 220 - age = Maximum Heart Rate. Maximum Heart Rate. An example for a 40 year old person would be as follows: 220 - 40 = 180 beats per minute (Maximum Heart Rate) A Low Fitness Person would train at 50% to 70% of 180 beats per minute which is 90 to 126. ................
