HIIT, short for High-Intensity Interval Training, has always been a very popular workout routine for people who want to build muscle endurance or lose weight.

This fitness routine has gained so many supporters because of the many benefits it can do for your body in just a short time. So what does this famous fitness training stand for?

Read on to learn more about this regimen, its benefits, and some easy workouts you can do.

What is HIIT?

HIIT is a cardio workout that involves alternating between high-intensity and low-intensity periods. You can do HIIT with any type of cardio exercise such as jumping rope, rowing, squatting, or running.

You will be sweating in no time in just a short period because of working out at an intense level and then cooling off for a slower recovery time and another round of high intensity afterwards. The work and rest intervals can last however you want, but each session lasts no longer than 20 minutes.

Doing this will help you burn fats, boost metabolism and build muscle endurance. Your body will also burn calories even after your workout—no wonder why this cardio training is trendy amongst fitness enthusiasts.

Benefits of HIIT Workouts

HIIT has become very popular in the fitness world because this training can give you lots of benefits in just minimal time. It can also be tailored for people of all fitness levels or those with medical conditions. Here are some proven benefits of why HIIT workout works.

1. Increases metabolic rate for hours after HIIT workout.

One of the known benefits of doing a HIIT workout is that it can help you burn calories even after you are done working out. Some studies have shown that it can boost metabolic rate for hours after a HIIT exercise. Researchers also found that HIIT could change the body’s metabolism to using fat for energy instead of carbs.

2. Can help retain muscle mass.

Though HIIT is not the best exercise to build lean muscle, it can help in retaining muscle mass. These workouts allow a person to preserve muscle while ensuring weight loss comes from fat stores.

3. Helps burn calories.

Performing HIIT workouts can burn more calories than a steady-state cardio exercise such as running, where your heart rate stays stable. It can burn 5 to 30% more calories than other forms of workouts.

HIIT can also burn calories even when you are done exercising. This occurrence is called excess post-exercise oxygen consumption or simply known as EPOC. EPOC happens when your body burns more calories rebuilding the wear and tear from intense training.

4. Enhances oxygen and blood flow.

HIIT workouts can enhance oxygen and blood flow. This is because your heart pumps blood through your circulatory system to transport oxygen to your organs and muscles.

A 7-week study in 2017 split two groups of children between doing a HIIT workout and a traditional exercise. The result was that the children who performed HIIT training improved their cardiorespiratory capacity compared to the ones who did a more conventional workout.

5. Reduces blood pressure and heart rate.

People who are overweight or obese can benefit greatly from doing HIIT because it can reduce blood pressure and heart rate. Some studies found that HIIT is a more effective exercise to lower blood pressure than moderate-intensity exercise.

If you want to improve your heart health, HIIT may be a significant part of your treatment plan. On the other hand, incorporating HIIT into your fitness routine may help maintain a healthy blood flow for people with normal blood pressure.

6. Saves time.

One of the good things about doing HIIT is it saves time. If you are a person who finds it a challenge to make time to work out, HIIT is a perfect option for you.

HIIT only takes a maximum of 20 to 30 minutes, and it is ideal for people who can only commit a few minutes of their time to exercise. You will get many health benefits in a shorter time than you would in a longer workout.

What Does a Typical HIIT Routine Look Like?

A typical HIIT routine will take about 10 to 30 minutes in duration. Even though it is a shorter form of workout, the benefits you can gain from it are the same or even twice as much as a moderate-intensity workout.

There are various ways to do HIIT, such as biking, sprinting, bodyweight exercise, or other cardio exercises. One example of a HIIT workout is by using a stationary bike that involves 30 seconds of cycling with high resistance and then easy cycling afterwards with low resistance. This is considered one round of HIIT; you will usually complete it by doing 4 to 6 repetitions in one session.

Remember that a HIIT workout involves short periods of intense exercise that will make your heart rate accelerate, followed by a slow recovery period. The particular time you exercise and rest period varies depending on the type of activity you choose and how strongly you exercise.

Types of HIIT Workouts

HIIT workout can be any type of exercise as long as you do intense movements for a short period followed by a more extended period of slow recovery. There are different HIIT workouts, including cardio HIIT, HIIT with weights, bodyweight HIIT, and full-body HIIT.

If you are just starting with cardio HIIT, you may try doing bear crawls, side kicks, or push-ups. If you think you can do more challenging exercises, then you can do a plank with hip dips, crusty lunges, or handstand push-ups.

HIIT with Weights

  • Kettlebell swings
  • Deadlift & row
