Any workout that alternates between intense bursts of activity and defined times of less-intense activity or even complete rest is known as high-intensity interval training (HIIT).

What Exactly Is High-Intensity Interval Training (HIIT)?

Short bursts of high-intensity exercise are alternated with low-intensity recovery periods in HIIT. Surprisingly, it is maybe the most time-efficient method of exercise.

A high-intensity interval training program usually lasts 10 to 30 minutes.

Despite its brief duration, the workout has the same health advantages as twice as much moderate-intensity exercise.

High-intensity intervals, regardless of how they’re done, should involve short bursts of hard activity that raise your heart rate.

HIIT not only provides the benefits of longer-duration exercise in a fraction of the time, but it may also bring some distinct health benefits.

1.It Burns a Lot of Calories in a Short Amount of Time

A study showed that HIIT burns 25–30% more calories than other forms of exercise.

You burn about the same amount of calories doing a
high-intensity interval training workout as you would doing a traditional workout like running.

A HIIT workout, on the other hand, burns more calories than a steady-state cardio exercise like running, when your heart rate remains relatively constant.

2. HIIT Strengthens a Variety of Muscular Groups

The majority of high-intensity interval training workouts include a variety of activities. This allows you to work out different muscle groups at the same time.

For example, a HIIT workout may include squats, push-ups, and burpees, all of which target distinct muscles.

A 2017 study discovered that for overweight females teens, a 12-minute HIIT training had a greater effect than a 40-minute aerobic activity.

This was determined by monitoring irisin levels, a hormone secreted by muscles in response to exercise.

3. Boosts Oxygen and Blood Flow

The ability of your muscles to use oxygen is referred to as oxygen consumption, and endurance training is commonly used to improve oxygen consumption.

Your heart circulates blood throughout your body, delivering oxygen and nourishment to your muscles.

HIIT activities have also been shown to assist and even boost your circulatory system.

4. It Has the Ability to Lower Heart Rate and Blood Pressure

It has been shown in numerous studies to lower heart rate and blood pressure in overweight and obese people.

According to certain studies, high-intensity interval training can lower blood pressure even more than the commonly advised moderate-intensity exercise.
