High Intensity Interval Training Workouts to Lose Weight

High Intensity Interval Training (HIIT) workouts for weight loss.

When it comes to weight loss, fat loss, and boosting your metabolism, high intensity interval training is the way to go.

You'll spend less time working out, and you'll achieve your weight loss goal faster.

High intensity interval training improves both your aerobic fitness as well as your anaerobic systems.

And because you'll be spending less time working, you preserve muscle loss, which is something that happens with long steady cardiovascular exercises.

Since muscles are one of the most important factor to keeping your metabolism running efficiently, this muscle preservation is essential. 

We covered this in great detail in our post, cardio vs weight training which is one is better for losing weight.

If you are not familiar with the differences between the two types of exercise, read the post and come back to this post for a short cardio workout.

So, what is high-intensity interval training (HIIT)?

High intensity interval training

High-intensity interval training (HIIT), also known as high-intensity intermittent exercise (HIIE), is a form of training that involves alternating between short periods of very intense anaerobic exercise such as sprinting for 30 seconds with less intense aerobic exercise such as walking for 60 seconds.

Example of high-intensity interval training:

  • Sprinting 30 seconds
  • Walking 60 seconds

In fact, this is what this 20 minute cardio workout is all about.

While you can perform this workout as a stand-alone and add sparingly or regularly to your workout routines, following this 4 week high intensity interval training program can bring optimum weight loss and fat loss results.

You'll you nedd to grab the 30-Day Workout Calendar to follow your weekly workout.   

Week-1 of The 4-Week

There are 3 parts to this cardio routine:

  • Warm-up
  • Interval Training
  • Cool down

How this plan works:


  • 3 Minutes - It begins with a 3 minute warm-up where you slowly and steadily raise your heart rate to Zone 1 target heart rate. 
  • Level of cardio during Warmup is easy and your quality of breathing should be very relaxed and can easily carry on a conversation. 

Interval Training

  • 14 Minutes - In Interval Training, you raise your heart rate to Zone 2 by increasing intensity.
  • Running faster can usually increase your cardio workout intensity. Level of exertion is moderate and talking should get difficult during this Interval Training. 


  • 3 Minutes - The purpose of this 3-minute cooldown is to slowly bring down your heart rate to Zone 1 to prevent dizziness when stopping an intense activity.
  • Use of a treadmill is an excellent way to add incline during your interval training, but if you don't have an access to one, you can use other types of cardio such as running outside or biking.

What's important is you aiming to reach your target heart rate zone during each phase.
