For individuals under 65, how many days a week should moderate-intensity aerobic exercises be performed?

1. 5 days

2. 3 days

3. 6 days

4. 4 days

The correct answer is: 5 days

For individuals under 65, the recommended amount of moderate-intensity aerobic exercise is at least 150 minutes per week, which can typically be achieved through performing such exercise on five days of the week. This guideline aligns with the physical activity recommendations from various health organizations, including the American College of Sports Medicine (ACSM) and the Centers for Disease Control and Prevention (CDC). Performing moderate-intensity aerobic exercise five days a week allows individuals to spread the recommended exercise duration throughout the week, making it more manageable and sustainable. This frequency helps improve cardiovascular fitness, maintain a healthy weight, and contribute to overall physical well-being. When exercise is distributed over five days, it also minimizes the risk of injury by avoiding the fatigue that may come with more intensive or prolonged sessions when performed less frequently.
