No matter how you choose to work out, the American Heart Association and the American College of Sports Medicine has issued new guidelines to help us get fit.
They suggest either vigorous exercise three times a week or moderate exercise five times a week. So what's the difference?
Dr. Jennifer Mitchell, who is in sports medicine at Texas Tech, was our guest Thursday on NewsChannel 11 at 5. She says if you can get your heart rate up and still talk, that's moderate exercise. But if you are unable to carry on a conversation while working out, that's vigorous exercise.
Dr. Mitchell says the biggest reason we fail in an exercise program is we try to do too much too fast. So she suggests setting both short term and long term goals.
