HIIT (High Intensity Interval Training) is a workout of successive intensive exercises and recovery periods.

Involving the whole body, HIIT is a complete workout aimed at improving Endurance, Cardio, Coordination and Balance.


The benefits of interval training (HIIT) are numerous, including: increasing endurance, improving acceleration and speed, and burning more calories in less time. Basically it makes you more athletic, faster, and accomplish 3x faster what you would on a treadmill!

Although most people know that physical activity is good for your health, it is estimated that about 1 in 3 people worldwide do not get enough. Physical inactivity is the fourth leading cause of death in the world.


So, unless you have a job that requires physical exertion, a regular workout is probably the best thing you can do for your well-being and your physical and mental health.

BONUS ! HIIT speeds up your metabolism and allows you to burn fat for hours after your workout is over.



HIIT burns a lot of calories quickly1. 


One study2 compared the calories burned over 30 minutes of HIIT, weight training, running and cycling.


Researchers have shown that HIIT burns 25-30% more calories than other forms of exercise. In this study, the HIIT session consisted of exerting a maximum of 20 seconds, followed by 40 seconds of rest. This means that participants actually exercised only a third of the time that groups of runners and cyclists were exercising.


Although the duration of each workout was 30 minutes in this study, it is common for HIIT workouts to be much shorter than traditional exercise sessions. This is because HIIT allows you to burn the same amount of calories, but in less time.


One of the ways that HIIT helps you burn calories is post-workout.


Several studies have demonstrated the impressive ability of HIIT to increase metabolism hours after training3.


Researchers have even shown that HIIT increases your metabolism even more after the workout compared to jogging or a regular weight lifting session4. In the same study, it was shown that HIIT, above all, causes a greater consumption of fat.


Another study also showed that just two minutes of HIIT in the form of sprints increased metabolism for 24 hours, which was energetically equivalent to 30 minutes of running5.

Thanks to a significant increase of the metabolic activity, HIIT generates a post-workout calorie burning called EPOC (excess post exercise oxygen consumption), which burns 6 to 15% additional calories.



Studies have shown that HIIT can help with fat loss.


In June 2017, a review of 13 experiments involving 424 obese or overweight adults was published. Interestingly, it revealed that HIIT and traditional moderate-intensity exercise can reduce body fat and waist circumference.


In addition, a study found that people who did HIIT three times a week for 20 minutes lost 2 kg of body fat in 12 weeks without dietary change. The most interesting parameter is undoubtedly the 17% reduction in visceral fat (pathogenic fat that surrounds internal organs).


Several other studies also indicate that it is possible to reduce body fat with HIIT, despite the reduced training time678.




In addition to helping lose fat, regular HIIT practice helps build and tone muscle mass.


Of course, the legs and the core (abs and back) are the first muscle groups to benefit from a noticeable improvement9. That said, a full body HIIT workout will tone all the muscles from head to toe.


Even though classic weight lifting training is the most effective way to gain pure mass, the practice of HIIT is preferred by women who are more inclined to tone their muscles rather than increase their mass10.

Bottom line: HIIT allows you to burn a lot of calories without losing muscle mass unlike long endurance training.



Oxygen consumption refers to the ability of your muscles to use oxygen. This parameter is also called VO2max.


Endurance training is typically done to improve it, but HIIT has been shown to achieve the same benefits in less time11.


Two studies have confirmed that to achieve the same level of improvement in oxygen consumption, it takes 2x less time to practice HIIT-type training than conventional training such as stationary cycling.


The first study reported a 9%12 gain in 5 weeks with 4 weekly 20-minute HIIT workouts versus 40 minutes of continuous cycling. The second 8-week study reported a 25% gain13 revealing the same ratio of half the time for HIIT.

Here you are, convinced that HIIT is for YOU!
