Every plan is evidence-based, personally tailored and focused on getting you back to the life you want to live.
Swanbourne
Our Swanbourne Movement Studio is the main base for Caitlin our clinical lead, who delivers one-to-one exercise physiology consultations here — a boutique clinical experience for clients seeking expert assessment, precise programming & measurable outcomes. It’s also where we run small-group yoga, Pilates, strength & tai chi classes, each grounded in exercise physiology & led by qualified practitioners who adapt every session to your body, history & goals. Ideal for clients managing injury, rebuilding after setbacks, or training smarter after years of generic gym programs.
North Fremantle
North Fremantle is our flagship exercise physiology clinic and the home of our baseline testing lab — where university-qualified Accredited Exercise Physiologists use clinical-grade assessment tools to measure exactly where your body is now, and build a personalised exercise and lifestyle program from there. Whether you’re recovering from injury, managing a chronic condition or optimising your health for the decades ahead, every program we design is grounded in objective data and tracked against measurable outcomes.
WELCOME TO O2 ACTIVE
Clinical exercise physiologists, performance testing and physiotherapists
O2 Active is an accredited exercise physiology and physiotherpay practice with the most comprehensive clinical testing suite of any EP practice in Western Australia. VO2 max and metabolic testing, lactate threshold, metabolic testing, running analysis, VALD movement screening, force-plate strength assessment — we measure what matters, then build your program on the results.
Whether you’re managing a chronic condition, rebuilding after illness or injury, or investing in how well you age, our university-qualified exercise physiologists work from objective data — not guesswork. Every program starts with a baseline, and every review shows you exactly what’s changed.
We liaise closely with GPs and medical specialists across Perth, providing objective, measurable feedback on chronic health conditions and health optimisation. Your referrer doesn’t get a vague progress note — they get numbers.
We’ve been doing this since 2001. The relationships we build with our clients are still the reason it works.
The best program is built on real data about your body — and delivered by a clinician who knows you. We do both.

“Since coming on board with O2 Active in late 2021, I have found a great community of like-minded people that enable me to be authentically myself – both physically and mentally.
Working with Caitlin and her team has granted me a real eye opener of how physios and AEPs can work together and have a real role to play for all people, irrespective of their ability. From partaking in the Yin Yoga, physio treatments, to one-on-one exercise physiology and Pilates sessions, nothing has been too much for the staff at O2 Active. I am so happy to be working with Caitlin and her team and I can’t wait to see what more ability I gain in my everyday life.”
