What does an increase in exercise duration at lower intensity achieve?

An increase in exercise duration at lower intensity achieves the burning of more calories. When exercising at a lower intensity for an extended period, the body primarily utilizes fat as a fuel source, which can contribute to a higher total caloric expenditure over time. This type of exercise, often referred to as steady-state cardio, can be beneficial for individuals aiming for endurance and weight management, as it allows them to sustain activity for longer periods without excessive fatigue.

In contrast, shorter bursts of high-intensity exercise typically result in a higher calorie burn per minute but may not accumulate the same total calories as consistent lower-intensity exercise over a longer session. Thus, extending the duration of lower-intensity workouts can be an effective strategy for increasing overall calorie burn while still allowing for an achievable and sustainable exercise routine.
