Also keep in mind that its important to keep moving between the “hard” portions of your workout. All of the workouts discussed here involve the alternation of hard and easy efforts. “Easy” means a slow pace, maybe a jog. But it does not mean walking, stopping, or collapsing to the track and wheezing. If you need to do any of those things, you’re running the hard portion of the workout too fast. The old adage of “no pain, no gain” is simply wrong. The idea is to push only a little bit harder than your normal training pace to get the benefits; there will be some modest discomfort but certainly no pain. You should always have the energy after each interval to continue running slowly during the rest periods. By doing this, you keep your heart rate up, and as a result, you prevent blood from pooling in your legs. Keep running, even if slowly: its good for you.
