Who We Are

Sterling Results Fitness Club was established by Sonia Wray. At 52 years of age Sonia realised that to a live healthier and happier life was an important factor to aging; as such she transformed her career from a senior executive to a Personal Fitness Trainer, where her moto is being “Fit, Fabulous and Over 50”.

After completing her certifications Sonia focuses on clients just like her, those who are, or who want to be ‘Fit, Fabulous and Over 50’. Sonia’s philosophy is to hire trainers who are of similar background or appreciate the needs and challenges of the targeted clientele.

Sonia is a lover of trekking high altitude mountains and golf, as such she has designed programs specifically focused on these areas. Since founding Sterling Results Fitness Club, Sonia has repeated the benefits of living a healthier and fitter lifestyle, she has reduced her cholesterol and blood pressure readings, lost over 10kg, dramatically changed shape and is a much healthier post-menapausal women!

Sonia witnessed too many people struggle physically when going on their adventures of a lifetime, as such she wanted to help those embarking on a trek to be physically and mentally prepared. She loves helping clients get fitter in nature through her HIKEfit Program as well as building clients resistance to bone damage through her personal fitness training.

What Our Client Say

I wanted a challenge for my sixtieth year and set my sights on hiking the Overland Track in Tassie. I wanted to enter my next decade fitter than the last! Around a year ago I joined Sonia’s Hikefit program. I’m now fitter, stronger and more confident and I’ve met some wonderful people on our weekend hikes. And this week I have a grin wider than the mountain ranges I’ve just traversed on the Overland Track – we smashed it!

“My gym closed down as a result of Covid-19 and a friend suggested I joined Sterling Results Fitness Club online classes. I live in Adelaide and SRFC is in Sydney, but I thought I’d give it a go. In the end I attended between 2-4 classes every week online for 8 weeks.

Sonia the trainer (and owner) did a fabulous job, I really felt apart of the classes (even over Zoom), getting the necessary adjustments if I wasn’t doing a move correctly, and most importantly getting me the motivation I needed to keep fit!

I would highly recommend Sonia and SRFC, a great boutique club worth joining! :)”
