Gemma O’Brien

NSW Fitness Coach

As a former student of AIF, Gemma immediately knew that she wanted to one day share her knowledge of the industry and educate others in the field of health, fitness, strength and nutrition. She loves to see people do things they never thought possible and help them reach their potential.
During her career, Gemma has worked at over 16 gyms throughout Australia in the role of both manager, Personal Trainer, and Coach, and gained valuable experience in the day to day running of gyms. She has worked with a wide variety of clients including athletes, rehab, weight loss and body transformation in both the Personal Training space and Group class environments. In 2020 Gemma decided to branch out even further and start a boutique online coaching and mentoring business to work alongside her already active face to face Personal Training and coaching business.
Gemma’s main passion is strength sports and has competed in most of these disciplines including bodybuilding, powerlifting, Strongwoman, and more recently olympic weightlifting – where she competed and won silver for Australia in 2019 in Montreal, Canada.
