That small weight loss changed her mindset towards exercise and she then joined a gym.
Embracing powerlifting, the Queensland woman went on to lose another 25 kilos before taking up CrossFit.
But while she embraced exercise, she found it impossible diet – so she focused on fitness rather than obsessing over the food on her plate.
Now at 70 kilos she shares her top tips for losing weight and keeping it off.
Surround yourself with supportive people
‘My biggest to stay motivated throughout your journey is to find either a personal trainer/coach, a gym buddy or your partner to join this amazing experience with you,’ Chenai tells New Idea.
‘It means you not only have someone to motivate you on the days you don't quite feel like going, but also someone to keep you accountable when you haven't gone to the gym in a few days.
‘Your perception on training will go from ‘oh I'm just going for me’ to ‘I go for us’.’
Always try new things
‘You wouldn't eat foods you don't like. Then why would you keep rocking up and doing things at the gym that you also don't enjoy?’ Chenai asks.
‘Trying new and exciting styles of training will keep you from getting bored and ensure you look forward to each and every session,’ she says.
‘I've tried a lot of different sports and training styles throughout my journey with a range of different coaches - from powerlifting, swimming, cross county running, agility/HIIT all the way to cross fit.
‘From there I figured out what I loved and what I loath from each style and just continued to train from what I got the most enjoyment out of.’
Have a strong and clear goal
Knowing where you want to be in six weeks, three months or even a year will bring you so much more dedication and drive,’ Chenai says.
‘You will know where it is you’re going and writing down these goals will give you strong stepping stones in order to make sure you commit to reaching those miles stones.
‘When setting goals, start with small realistic and achievable steps and know this change in habits is not a quick fix it's a lifestyle.
‘So committing to train three times a week and only have two cheat days to begin with is achieveable over three to 12 weeks.
‘If you do more than what you have set out to you will feel more accomplished and motivated to stay on track!
‘Then increase the training days and be disciplined on your food intake
‘Setting to high of standards will result in you missing your goals one day and then the next day, that will eventually cause you to be unmotivated and perhaps stop you from continuing in positive actions towards your weight loss and fitness journey!’
