My doctor told me to get more exercise, but I don't have much free time. How much exercise do I need to do?

It depends on your current activity level and how you want to improve it. If you are currently sedentary or moderately active, then 30 minutes of moderate-intensity aerobic exercise per day is recommended for optimal health. This could include walking, jogging, biking, swimming, or other activities that elevate your heart rate. You can also try to incorporate strength training into your routine as well, which will help build muscle mass and increase your metabolism.
