Zone Two: Fat Oxidation and Aerobic Energy Production

Zone Two is characterized by low to moderate intensity exercise where the body primarily utilizes fat as a substrate for energy production. The aerobic oxidative phosphorylation system is predominantly used, with energy produced within the mitochondria. At this intensity, fat is the primary fuel source with some glucose utilization. Heart rate can be calculated using various formulas, such as 220 minus age, but individual variations may occur. The goal is to maintain a heart rate within a range of approximately 60-70% of the calculated max heart rate.
