Operating at a lower intensity affects calorie burn by reducing the overall amount of energy expended. While low-intensity workouts burn fewer calories per minute than high-intensity ones, they can still contribute significantly to total calorie expenditure if performed for longer durations. Additionally, low-intensity exercise promotes better fat oxidation, potentially aiding in fat loss. It also allows for longer sessions, making it easier to stay consistent and recover faster, which is beneficial for overall fitness. This approach can be particularly suitable for beginners or those with certain health conditions.
