I am quite a physically active person, participating and competing in sport from a young age. I have grown up understanding the importance of a physically active and healthy lifestyle, something that I have become very passionate about. As a teenager I was able to compete in the sports of swimming and hockey at an elite level, an experience which taught me a great deal of responsibility and discipline. Since my teenage years I found a joy in participating in CrossFit in my spare time. I like to be disciplined and I enjoy challenging myself with new targets that I set my sights on. My competitive nature means that I can’t resist the friendly rivalry with other like-minded CrossFit devotees.

Currently completing my Masters of Clinical Exercise Physiology at Curtin University, I’m particularly interested in ways in which exercise can be used as a modality of treatment in regards to cardiovascular, metabolic, musculoskeletal health, and other complex and chronic conditions. I have a passion for sport and physical literacy and enjoy helping people succeed in their physical pursuits as a result of my influence. I find great satisfaction in watching people achieve their physical movement goals, whether they be big or small.

Amy Ross

After discovering a passion for fitness while studying Psychology at UWA, Amy recently commenced Sports Science Exercise Rehabilitation Science studies at Curtin University. With an original goal to enter Sport Psychology, her love of everything health and fitness made her reconsider her study choice and felt as though Exercise Physiology was more of an appropriate choice.

Amy is involved in competing her horses in dressage and she involves herself in non-competitive running.

Having so many influential coaches and role models in her life, Amy appreciates that the fitness journey is often the most successful when supported and pushed by those leading examples and finds its important to be constantly pursuing goals.

Julian takes a holistic person-centred approach to exercise, where the biopsychosocial domains of health that comprise the individual are recognised and supported. His keen interests for all aspects of training and healthy movement, combined with personal application of the knowledge backing his sessions, complement his goal of helping people realise their own potential day in and out.

I began dancing at the age of 3 and have trained in a range of genres including RAD Ballet, Jazz, Tap, Hip Hop and Contemporary. I have been involved in summer intensives with Co:3 Youth Dance and as well as classes with Sydney Dance Company and Brent Street Performing Arts as part of PLC’s Dance Tour to Sydney in April of 2019. I was Dance Captain at PLC in 2019 and upon graduation received the prize for the top mark in ATAR Dance. This year I started working at Silhouette Dance Studio where I have continued to gain teaching and choreographic experience with a variety of age groups. Over the past couple of years, I have developed a strong interest in fitness and particularly its importance for dancers in maintaining the health and condition of their bodies in a gruelling profession. I find teaching extremely rewarding and love to see my students learn and explore their talents whilst having fun.
