FitSugar has a simple and effective tip to share: Really push yourself for five minutes of your workout.

My favorite exercise is a cardio DVD that I follow in my living room. Without realizing I was doing it, I often follow FitSugar's tip. I use the weights for a while longer than the instructor, I pump up the intensity, or add some of my own moves to make the workout just a bit more challenging.

Whatever your workout of choice is, try adding five minutes of high intensity activity. Push yourself and let your body get a little winded. Unless you have asthma or another condition that contraindicates you for this type of high-intensity exercise, the change in pace will be good for your workout.
