Her journey has only just begun, but a Gunnedah woman has already reached success after completing Michelle Bridges' 12 Week Body Transformation program.
Cath Riley has already lost almost 14kg through the program alone, but she isn't stopping there, she wants to keep up the lifestyle change.
"I just did it for myself, just to make me feel better in my own skin," she said.
"Losing weight takes pressure off; you pick 14kg up and it's a lot to carry around. It releases pressure on your joints."
She now eats well, exercises regularly, and is proud of her "newfound muscle definition".
"One of my main goals was to tone my body and I can now see the physical changes. I've found greater physical and mental strength," Ms Riley said.
"When I eat out, I can now determine the healthier options on the menu. I've always enjoyed cooking and now I can make healthier options for myself and the whole family.
"One quirky thing that has helped me is I use smaller plates for meals, so I never feel like I'm going without."
As we age, it's just good to try and maintain what we've got and keep healthy.Cath Riley
Ms Riley was one of 300 people who took on the challenge when it began in the New England area in September.
Over the 12 weeks, participants followed Bridges' nutritionally-balanced meal plans, recipes and tailored workouts. Mindset videos and regular weekly emails guided them along the way, and they all had access to Rural Fit gyms.
Ms Riley said her new lifestyle was important because "as we age, it's just good to try and maintain what we've got and keep healthy".
"I've got a mum who's suffered from osteoporosis and she has dementia so I think it's important to keep busy and keep on track the older we get. If we can ward off anything untoward then that's a good thing," she said.
