ABC Your Transfer: What’s a HIIT class and the way can doing one assist your well being and health?
Because the ABC launches the Your Transfer marketing campaign to assist Australians discover their well being and health journey, reporter Marnie Vinall hits the highway to strive among the rising train traits across the nation.
As one of the vital widespread health traits going round, I believed I would give high-intensity interval coaching (HIIT) a bench check.
- HIIT classes contain brief, sharp bouts of train at most effort, with brief restoration occasions
- The classes embody workouts resembling tuck jumps, sit-ups, tricep dips and lunges
- Lessons are sometimes accessible at gyms and are touted as being handy and time efficient
This would not be my first rodeo with high-intensity workouts.
Throughout the six lockdowns of Melbourne, I went by means of a YouTube dance HIIT part, the place I might squat and soar alongside to Hamilton and Disney songs, blindly following a health YouTuber’s directions.
However this might be my first in-the-flesh group class – one the place I could not determine to skip strikes or train at my pleasure, or log out early deeming I had sufficiently already executed sufficient.
This time, I would have nowhere to cover.
As my native health club already presents most of these courses, I made a decision it could be a secure and handy wager to road-test the favored train format.
However first I acquired involved with John Hawley, director of the Mary MacKillop Institute for Well being Analysis on the Australian Catholic College, to ask what HIIT was all about.
“Excessive-intensity coaching and interval coaching have been round for years for athletes, nevertheless it’s solely not too long ago that they’ve turn out to be widespread for common well being,” he mentioned.
The thought behind it’s “very brief, high-intensity bursts” of train adopted by brief intervals of relaxation.
For instance, 10 minutes of high-intensity work with one minute of restoration between every set for 20 minutes.
“Now, what’s excessive depth? Nicely, it is one thing that just about you’ll be able to solely do for a minute, after which it’s important to cease,” Dr Hawley mentioned.
It entails workouts like tuck jumps, planks, soar squats, leaping jacks, sit-ups, tricep dips and lunges — all geared toward growing your coronary heart fee to 80 per cent.
Dr Hawley advised me these workouts had cardiovascular advantages as a result of coronary heart fee being tremendously elevated, whereas growing power to the muscle tissue used from pressure or resistance positioned on them.
“You are getting a very good bang on your buck,” he mentioned.
“You are making use of a really potent stimulus to rework the cardiovascular and muscular system.”
Moreover, numerous analysis has related HIIT with improved cardiovascular and metabolic outcomes, together with elevated health, weight reduction and improved blood stress and inflammatory markers.
So I took myself to the health club for a late afternoon HIIT class to see how I would go together with these brief bursts of excessive depth adopted by – what I assume for me in my first go – ferociously sucking again within the oxygen.
The category was break up into three sections with drink breaks in between. Every part lasted round quarter-hour and was crammed with 45-second bursts of workouts, which ranged from excessive knees and bum kicks to burpees, squat holds and planks.
I began fairly confidently, grabbing a weight to carry in the course of the lunges after which jogging on the spot between workouts nevertheless it did not take lengthy for the fatigue to set in. About 20 minutes in, I dropped the burden and simply tried to maintain up and push by means of the ache.
Though, 45 seconds had by no means actually felt longer than when doing glute holds or burpees interspersed with push-ups. I used to be grateful for the brief breaks between workouts.
I used to be dreading one other spherical of squat holds when the trainer declared, ‘You probably did it!’ and guided the room right into a collection of stretches earlier than letting us go. These included runner’s lunges, pec, hamstring and quad stretches and kid’s pose to launch the again.
I used to be red-faced and sweaty however pleased with my effort. The time did go shortly and I may see what Dr Hawley was speaking about when he mentioned it was an environment friendly type of train. My complete physique, plus my cardiovascular system, felt prefer it acquired a exercise.
So, I took my shaky legs residence, going further slowly down the steps on the way in which out, and hopped straight in a heat salt bathtub as a reward.
Dr Hawley mentioned for non-professional athletes, refuelling didn’t want an enormous focus, however an enormous meal and loads of water ought to do the trick.
Additionally, that he would advocate not solely doing HIIT courses however combining them with different types of coaching, resembling endurance-type workouts like swimming, working or biking. And to all the time attempt to get a quiet down in to assist take away lactic acid from the physique and pace up restoration.
For now, I am simply going to concentrate on the restoration sleep.
HIIT stands for high-intensity interval coaching, the place contributors full brief intervals of explosive train at most effort with very brief intervals of relaxation between — historically about 20 seconds on, 10 seconds off, though these timings do change and might prolong as much as a minute or barely longer.
These explosive train intervals are executed underneath anaerobic situations, which mainly means “with out oxygen”. Which means you’ll be able to’t do it for so long as cardio train.
Consequently, train classes of this sort usually final about half-hour.
The sort of train burns glucose and creates a build-up of lactic acid.
How a lot does a category value?
HIIT courses are sometimes mixed with a health club membership or as a part of a six- or eight-week pack, which may value something from $150 or $200.
The place can I do HIIT?
Gyms that provide HIIT courses are pretty commonplace — simply search HIIT to seek out your nearest health club, or to discover a class you just like the look of.
