We get so many questions about HIIT; it’s probably one of the most popular topics. I suppose that could be because Mark and I, along with Dr Jim Stoppani, wrote one of the leading HIIT books in the industry. We actually like to include this book for free when people buy FitnessGenes™ DNA Performance Kit, but we are running in short supply.

Let me just summarise HIIT…

HIIT (High Intensity Interval Training) involves training at a very high intensity in an interval format. There are tonnes of performance-based benefits you get with HIIT because of the skeletal muscle changes similar to that of endurance training. The reason it has such acclaim this day in age is because we now know that HIIT is great for burning body fat.

Here’s why…

When you have lots of oxygen around, your body uses aerobic energy pathways. When oxygen runs out, it uses anaerobic energy pathways. HIIT is an anaerobic form of exercise that seems to help boost metabolic rate by increasing something called EPOC (Excess Post-Exercise Oxygen Consumption), and also possibly increases the VO2 max, which allows the body to process more calories and oxygen.

When you create an oxygen debt, as represented by the EPOC, your body has burnt off all available sugar, so it starts to burn fat. As a result of HIIT, your body burns fat and continues to burn fat for many hours after the training session. And that’s really the basis of it.

So what does this have to do with genes and DNA?

Well I’m pleased you asked that. We test for genes that tell us how easily you burn fat. There are some genotypes where switching from carbohydrate to fat metabolism is not that easy. For these people, burning fat can be really difficult, so they need to be doing HIIT as part of their fat loss training, unquestionably. We can even give these people an idea of the amounts of HIIT they should do.

Pretty impressive, right?

But what do you expect, as I’ve said this time and time again: your DNA is a blueprint. If you understand your DNA and decipher it appropriately, then you literally have a road map to your goals… even surpassing your goals!
