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

It depends on your fitness level and goals, but generally speaking you should aim for at least 30 minutes of moderate-intensity aerobic activity such as walking, swimming, cycling or other aerobic activities three times a week. Additionally, strength training exercises that involve all major muscle groups two times a week is recommended. Finally, make sure to include flexibility exercises like yoga, Pilates, or stretching at least once a week.
