Final answer:
The CDC does not have a specific recommended daily step count, but the Physical Activity Guidelines provide general recommendations for physical activity levels.
Step-by-step explanation:
The Centers for Disease Control and Prevention (CDC) does not have a specific recommended daily step count. However, the 2018 Physical Activity Guidelines for Americans, issued by the Department of Health and Human Services, provide general recommendations for physical activity levels. For substantial health benefits, adults should aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity activity per week. In addition, they should also engage in muscle-strengthening activities on 2 or more days per week.
