According to federal guidelines, how much time should an adult perform moderate exercise each week?

Federal guidelines recommend that adults engage in moderate-intensity aerobic exercise for at least two and a half hours each week to achieve significant health benefits. This duration is aimed at improving cardiovascular health, maintaining a healthy weight, and reducing the risk of chronic diseases.

Moderate exercise can include activities like brisk walking, dancing, or gardening, where you’re working hard enough to raise your heart rate but can still hold a conversation. Meeting this guideline is a foundational element of a healthy lifestyle, supporting physical fitness and overall well-being.

The other response options fall short of the established guideline. For example, three hours exceeds the minimum recommendation, while thirty and twenty minutes per session are less than the cumulative weekly total needed to meet the guidelines for moderate exercise. Therefore, the two and a half hours stands out as the correct recommendation for weekly moderate physical activity.
