When you exercise regularly the increased aerobic capacity allows to be used for fuel so that is spared?

When you exercise regularly, your body enhances its aerobic capacity, which improves its efficiency in utilizing oxygen for energy production. This allows your body to preferentially use fat as a fuel source during prolonged activities, thereby sparing glycogen stores. As a result, you can sustain exercise for longer periods without depleting your energy reserves, ultimately improving endurance and performance. This shift in fuel utilization also aids in better weight management and overall metabolic health.
