Jacqui Main

Senior Accredited Exercise Physiologist

Growing up in the country with three brothers, Jacqui has always had a passion for sport and the outdoors, playing a range of different sports. After suffering an anterior cruciate ligament (ACL) rupture at 17, Jacqui developed a passion for rehabilitation through exercise and pursued this through her sports science degree.

Jacqui was always a keen sports person until she was diagnosed with pericarditis in 2007 from over-training, which resulted in her developing chronic fatigue syndrome. With her world turned upside down and being unable to work or to play sport, Jacqui had to transform her life and set new goals. This learning experience has enabled Jacqui to help clients going through similar experiences to achieve their work and social goals, no matter how big or small.

Jacqui’s belief is about movement and exercising into a healthier lifestyle and she has a ‘think outside the square’ approach to rehabilitation, making it functional and fun. She creates a friendly environment where people of all ages and fitness levels can feel comfortable achieving their goals. Her passion for exercise physiology assists others to achieve optimal functioning and quality of life.
