The most effective exercise level for an aerobic program aimed at weight loss generally includes a moderate intensity that supports sustained activity over a longer duration. Engaging in activities at less than or equal to 60% of maximum heart rate for 45 to 60 minutes, 5 to 7 days a week, allows individuals to maintain a manageable exercise program that promotes fat oxidation and overall energy expenditure.

This lower-intensity approach is particularly suitable for weight loss as it encourages prolonged aerobic activity, making it easier for individuals to adhere to their exercise routine. It also minimizes the risk of injury and fatigue, allowing individuals to maintain consistency, which is critical for achieving weight loss goals. Additionally, extended sessions at moderate intensities can enhance cardiovascular fitness and support metabolic health over time.

Higher-intensity options, while effective for improving fitness levels, may not be sustainable for everyone, especially those starting their weight loss journey. Such programs might lead to quicker fatigue, decreased motivation, and potential injury due to the stress placed on the body during high-intensity workouts. Therefore, option A represents a balanced and effective strategy for weight loss through aerobic exercise.
