Kusal says that reaching 85 per cent intensity in that short burst of time – with skipping, sprinting or star jumps – is as effective as 30 minutes of low-intensity exercise.
While you might be sceptical about the benefits of such a short workout, High Intensity Interval Training (HIIT) has long been lauded. A 2014 study found that those who did HIIT were more likely to enjoy them over longer, lower-intensity options, that might have something to do with recent research revealing the enormous endorphin rush it offers.
And it’s not just the euphoric feels, you’ll also be pretty stoked with the results. HIIT has been found to burn more calories during the workout, as well as 24 hours after it.
Best part? You can get one done in the time it takes for the kettle to boil.
