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! :)”
