The recommended amount of physical activity for adults each week is at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise. This guideline is set by health organizations to help maintain overall health and reduce the risk of chronic diseases such as obesity, heart disease, and diabetes. In addition to aerobic activity, adults should also engage in strength-training exercises on two or more days each week, targeting major muscle groups. Combining these activities supports physical fitness, mental well-being, and overall longevity.
