What the heck is HIIT?

HIIT: High intensity interval training – a technique that’s earned its name as the hottest training method on the market. It’s fast, intense and said to burn calories like nothing else, but what is it that actually makes this method of training so effective? If you’re still unsure of what really goes into a HIIT workout and which calorie-burning processes are triggered within the body as a result, you’re about to find out. Let’s finally answer the question many have been dying to ask: What the heck is HIIT?

What’s behind HIIT?

HIIT is a training approach that involves repeated bouts of high intensity working periods followed by varied recovery times, mainly boosting the metabolism as well as maximizing the oxygen intake. To get a better understanding of what we mean here, it’s important you grasp these two key points:

  • High intensity working periods: High intensity means your heart rate is at 85% to 100% of your individual maximum heart rate during training.
  • Recovery times: During the rest period, your heart rate should be between 40% and 50% of your individual maximum heart rate.

Why is this so important and what does it have to do with boosting your metabolism and maximizing oxygen intake? Let’s find out:

What are the benefits?

During the high intensity working periods, the body experiences an oxygen deficit and needs to restore itself to pre-exercise level. It is this excess postexercise oxygen consumption – EPOC for short – that boosts the metabolism and results in 6-15% more calories being burned in comparison to an aerobic workout (we’ll give you an example of this later). Another interesting point to consider is that during a HIIT workout, the body is able to burn calories yet still maintain the building of muscle mass – meaning you get the best of both worlds. And that’s not even all: This boost in your metabolism has several more positive effects on your health that go beyond burning calories, such as:

  • lowering blood pressure
  • increasing cardiovascular health
  • stimulating insulin sensitivity which helps the exercising muscles to more readily use glucose for fuel to make energy
  • improving cholesterol profiles

But the fun facts don’t stop there: It’s also been proven that a twenty seven minute session of HIIT, three times a week – so in total 81 minutes – produces the same anaerobic and aerobic benefits as 60 minutes of aerobic cardio training five times a week – which is a total of 300 minutes. What’s the consequence of doing HIIT? Less time consuming, more results. #Winning

What does a HIIT workout look like?

There is no “standard” HIIT workout. Since it’s all about heart rate and intensity, a high intensity interval training workout can include any kind of sport or exercise, be it running, cycling, swimming or bodyweight training. But the two most popular methods are Tabata and Little. Here’s what they look like:

  • Tabata Method: Tabat is the most popular form of HIIT training. It takes only 4 minutes to complete, and is therefore the quickest of the three examples. How it works is simple: 20 seconds high intensity, followed by a 10 second recovery period, repeated 8 times. 20 seconds might not sound like long, but if you are going all out, that’s going to feel like the longest 20 seconds of your life! Trust us…tabata hurts.
  • Little Method: This method follows the structure of doing 60 seconds of high intensity followed by 75 seconds of low intensity recovery periods for 12 cycles. In total it’s 27 minutes of work.

HIIT training works. But only if you’re prepared to struggle, sweat and give it your all. If you’re not going all out, you’re not doing it right. Looking for maximum results along with a post-workout high like no other? Then go ahead, HIIT yourself – it’s worth it.
