The 18-minute fitness routine breakthrough

Quick exercise circuit

Get your best body ever, in less time than it takes to watch an ep of KUWTK

Women's Health Editor / March 30 2020

Strange but true: neurologists have theorised there’s a reason so many TED Talks go viral – they’re all held to an 18-minute limit; long enough to be meaningful, yet short enough to not bore you out of your mind. Trainer Idalis Velazquez teamed up with Women’s Health and used that

concept to create our revolutionary new workout, All in 18. It torches fat and sculpts lean muscle from shoulders to calves, in just 18 minutes a day. Intrigued? Read on. 

How does it work?
At the heart of the All in 18 plan is resistance training – resistance builds muscle, and muscle means you burn kilojoules after you stop moving. The plan can also help you stress less, sleep better and fend off type 2 diabetes and inflammation. As a mum with little time for herself, Idalis created each zippy routine with clock-watching women in mind. Even better? The sessions require just a pair of dumbbells and a mini-resistance band, and are scalable to every fitness level. They target those areas that we tend to struggle with the most: thighs, core, bum and the backs of the arms. Excellent. 

“After having my second child, I went through a period of not working out as often, and I lost strength and definition,” says Idalis. “I experimented with various methods until I found adding a resistance band to high-intensity strength-training exercises actually rebuilt and reshaped my body.” Science gives a big tick to these bands – studies show they increase muscle activation by about 20 per cent, especially in the glutes. And high-intensity resistance intervals? Research from North Dakota State University suggests they torch twice as many ilojoules as previously thought – more like 108 per minute. 

Disclaimer: these workouts are tough. But, having Idalis in your lounge room with you will make you push yourself. “I believe you work harder with a cheerleader,” she says. One more thing: a lean body isn’t just about exercise – what you eat affects your shape, too. So All in 18 comes with a 21-day meal plan to help clean up your eating. We’ve scattered a few handy food tips throughout by way of inspiration. 

Can you really get fit in just 18 mins?
Yep! Groundbreaking research by McMaster University pitted a 10-minute interval workout against a 50-minute cardio slog with incredible results. The 10-min exercisers tackled three sets of intense bursts with rests in between. The 50-min cardio peeps had to cycle at a steady, moderate pace the whole time. At the end of 12 weeks both groups had reduced their body fat by about the same amount, significantly improved their muscle health and increased overall cardiorespiratory fitness. 

So why did exercising five times as long not deliver better results? 

Intense exercise is more demanding metabolically, says study author Dr Martin Gibala – you experience more ‘afterburn’ from shorter, more ntense bouts. Of course, going longer than 10 minutes – Idalis prescribes you 18! – will get you better results. Follow-up research by McMaster Uni found shorter workouts tend to be uber-effective because they’re more enjoyable than long slogs –meaning you’re more likely to stick to them. “For sedentary individuals, a barrier to exercise is the notion that it’s not enjoyable. Failing to enjoy it can make it more difficult to stick to,” says study author Jennifer Heisz. This fun factor kicks in after a few weeks. To start with, the self-confessed couch-lovers in the short-bout group reportedsimilar levels of enjoyment to those in the longer slog group. But as training progressed, enjoyment for the high-intensity group increased – while levels for the long workout remained constant or nosedived.

And, who’s got time for a hour of sweating between work, kids, catchups and the million other things you do each day? That’s why we’ve designed this super fast program to be as effective as it is efficient. Just 18 minutes a day, six times a week.


Taster workout
Idalis designed the following workout exclusively for WH readers, combining five of her fave moves from All in 18. Two or three times a week, perform each move in order, with little to no rest in between; repeat the routine up to three times in total, resting 30 secs between rounds. To kick your metabolism into serious overdrive, complete the two-part finisher. In just six weeks, you’ll be happily surprised by the results.


Banded kickstand deadlift

Stand with your feet hip-width apart, a mini band around your thighs and a dumbbell in each hand; step your left foot back and raise up onto your toes (a). Keeping a flat back, bend forward at your hips and lower your body until the weights pass your knees; squeeze your glutes (b). Reverse the movement to return to start. That’s 1 rep; do 12 reps, then repeat on the other side.
