I'm trying to lose weight. How much exercise should I get each week?

It depends on your current fitness level and how much weight you want to lose. Generally, the more fit you are, the more exercise you need to do. A good rule of thumb is that if you're not active enough to sweat at least once a day, then you should aim for at least 30 minutes of moderate-intensity aerobic activity most days of the week. You can also incorporate strength training two or three times a week. For optimal results, try to combine both types of exercise in order to reach your goals.
