What is the recommended level of physical activity for adults?

The recommended level of physical activity for adults is at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise each week. This guideline is supported by numerous health organizations, including the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO).

Engaging in this level of activity promotes cardiovascular health, helps maintain a healthy weight, reduces the risk of chronic diseases, and improves mental health and overall well-being. Moderate-intensity activities could include things like brisk walking or cycling at a casual pace, while vigorous-intensity activities could involve running or high-intensity aerobics.

Other options suggest insufficient activity levels for maintaining overall health. For instance, focusing solely on strength training or engaging only in gentle stretching does not meet the comprehensive requirements for cardiovascular fitness recommended for adults. Significant health benefits require a blend of aerobic and strength-training exercises, thus making option B the most effective choice for promoting long-term health.
