From sleep to heart rate variability to exercise, we are all about tracking our health in order to optimize. Dr. Phil Maffetone explains that heart rate monitors are the most important tools “for developing optimal endurance and better fat-burning.” When doing aerobic exercise, it is important to develop an aerobic base which helps to build our endurance while reducing stress on the body. Dr. Maffetone shares the “MAF 180 Formula” which helps find our optimal training heart rate, making our exercise programs more effective. The formula starts with: “180 minus a person’s chronological age, which is then adjusted to reflect their physiological age as indicated by fitness and health factors.”
