It is currently recommended that you exercise for 30 minutes at least five times a week in order to receive the healthy benefits of exercise. If you are having difficulty fitting a 30-minute block of time for exercise, you can divide up this time into two 15-minute blocks or three 10-minute blocks of time throughout the day. Studies have shown that you can receive the same heart healthy benefits of exercise even if it is not a 30-minute consistent period of time. Additionally, there are many forms of exercise you can do that can lower your cholesterol, depending on your schedule.
