ABC Your Move: What is a HIIT class and how can doing it help your health and fitness?

With ABC launching the Your Move campaign to help Australians explore their own health and fitness journey, reporter Marnie Vinall is setting out to experience some of the growing exercise trends across the country.

As one of the most popular fitness trends, I thought I’d give High Intensity Interval Training (HIIT) a test bench.

This wouldn’t be the first rodeo with high intensity exercises.

During the six Melbourne lockdowns, I went through a YouTube dance HIIT phase, squatting and jumping along to Hamilton and Disney songs, blindly following YouTube fitness instructions.

But this will be my first group class – one where I can’t just skip movements or exercise to my pleasure, or check out early because I’ve already done enough.

This time, I have nowhere to hide.

Since my local gym already offers these types of classes, I decided it would be a safe and comfortable bet to test the popular exercise format.

But first I called John Hawley, director of the Mary McKillop Institute for Health Research at Australian Catholic University, to inquire about HIIT.

“Intense training and interval training have been around for years for athletes, but only recently have they gained prominence in the public health field,” he said.
