This sprint interval workout is a type of high-intensity interval training (HIIT) that helps build endurance, increase your anaerobic threshold, and burn more calories and fat both during and after your workout. For this workout, you'll have a longer warm-up (10 minutes) before going into four all-out sprints at a Level 9 on the perceived rate of exertion for 30 seconds each. Between each sprint, you'll recover at an easy pace for 4.5 minutes, giving you plenty of time to get ready for the next sprint.

You may need more warm-up time if your body doesn't feel ready for the first sprint. Take as much time as you need to get warm so you can avoid injury.


Keep in mind that all-out effort is very challenging and, if you're an advanced exerciser, your sprints really should be all out, leaving nothing else in the gas tank. The recovery times will allow you to refill your tank, pay back the oxygen debt, and do the next sprint.

If you're a beginner, an all-out effort is not going to be fun for you, so we recommend starting with a beginner interval workout to get used to how intervals feel. Then, gradually work your way up to this workout.

Another thing to consider is that HIIT sessions don't have to be running workouts. You can do this workout on any machine, set to a manual mode, or you can do this with any outdoor activity such as walking, running, or cycling. In fact, this kind of workout is probably easiest outside or on a stationary bike.

What is Interval Training and Why Does It Work?


Add a Dynamic Warm-Up

Try starting with a 10 to 15 minute warm-up of dynamic poses that move on every plane, such as:

  • lateral lunges
  • jumping jacks
  • butt kicks
  • high kicks
  • figure fours
  • knee hugs
  • arm circles

Treadmill Workout

If you are using a treadmill, you will want to build in more time around the sprint intervals, since it takes a bit for the treadmill to speed up and then slow down. Increase the treadmill speed about 10 to 15 seconds before the interval starts. It will take another 10 to 15 seconds to slow down at the end of the sprint.

After the Workout

Make sure you take the time to cool down and then do a thorough, relaxing stretch. This kind of workout is very challenging on the body, so make sure you fuel up, get your rest and follow up with a recovery exercise day like light jogging, strength training or some other type of cardio.

If you really go all out, you'll only want to do this workout about twice a week with lots of rest days in between to avoid overtraining.
