Rebel Wilson's trainer Jono Castano on the fitness mistake you might be making

If you're someone who often thinks 'I'll start on Monday' or 'this is my new year's resolution', celebrity trainer Jono Castano says that's a very common mistake when it comes to your health and fitness journey

The trainer, who has helped Rebel Wilson lose over 20kg and trains the likes of Rita Ora and Hugh Sheridan, says changing your habits should never wait.

"I am such a big believer in starting as soon as you decide to change your habits," Jono tells Yahoo Lifestyle.

"So for me, starting a new lifestyle in a fresh year or even a fresh week isn't something I would suggest."

Instead, the FitBit ambassador says you should start as soon as you are "comfortable and ready", but stresses to never go "too hard too fast".

"Otherwise, you aren’t setting yourself up for success. It's never too late to make a change for a healthier lifestyle and these don’t need to be drastic."

Jono, owner of Acero Training Series, suggests starting with small habits every day that you can eventually add on to.

"For example, if you wanted to start running you could add five minutes a day to your routine," he explains. "As the weeks go on, you'll get fitter and feel five minutes is too easy so you will push to 10 minutes. Eventually, you could run non-stop for 45 minutes.

"But, imagine adding that 45-minute run when you aren't conditioned to. It sounds daunting, right? Small daily habits and starting as soon as you decide to is the key, and using a device like a Fitbit to track your progress will highlight how you’ve improved over time."

When it comes to changes you might have to make to your lifestyle, Jono stresses he encourages his clients to make a longer-term change, which will involve birthdays, dinners with friends, anniversaries, and holidays.

"It can't be an all-or-nothing approach. Balance is always an incredibly important aspect when embarking on improving your health," he adds.

"If the changes you make can be taken with you through years to come, that's the ultimate goal."


When it comes to tracking your fitness, smart watches are definitely becoming more and more popular. But Jono wants people to make sure they are looking at more than just their daily steps.

"Even though steps are important, we need to look at health holistically. It’s great to hit 10K steps a day but we need to ensure we are hitting other health goals," he tells us.

"Using a smartwatch helps you to monitor your physical activity, sleep, nutrition and even stress."

On of the key things Jono tracks on his own Fitbit Sense is his sleep.

"Sleep is one that is so important to the recovery process," he explains. "Without sleep, you’ll find yourself tired each day and your body won’t have the ability to heal the way it needs to."

When it comes to the success of his celebrity clients, Jono says one of the best things Rebel did was declare 2020 her 'Year of Health' and keep herself accountable on social media.

"Making your goal public will keep you on track and motivated to do everything you can to get there," he says. "This doesn’t need to be a large-scale announcement, but even talking to your family and friends is a good step."

Speaking with Yahoo Lifestyle previously, Jono also said Rebel's consistency was a huge part of her weight loss success.

"I'd say her consistency has been the most important thing, if you're consistent and you're getting amazing results then it's just going to continue to show, even if it's not just in your appearance, but it's also going to help in bringing out the best in you," he said.

"We sometimes forget about what fitness and results actually does, it's not just about losing weight, it gives you so much more confidence."
