Both aerobic exercises (like walking, running, and swimming) and anaerobic exercises (such as weightlifting) are beneficial. Aerobic exercises improve cardiovascular health and endurance, while anaerobic exercises help build muscle strength. It's best to include a combination of both in your routine. Aim for at least 150 minutes of moderate-intensity or 75 minutes of high-intensity aerobic exercise per week, along with muscle-strengthening activities on two or more days a week.
