Meet Sophie

Sophie Marshall Holmberg is an internationally certified personal trainer through the National Academy of Sports Medicine (NASM), USA and FitRec, Australia. She began her fitness career over 15 years ago as a Women’s Boot Camp and Body Sculpt Instructor in California, USA. Sophie was trained in fitness instruction and PT by her mentor, former Miss Galaxy, Miss Fitness USA and World Tri-Fitness Champion, Cynthia Hill.

Now in her mid 40’s, Sophie understands the challenges of staying fit and healthy through mid life and beyond and is dedicated to helping women of all ages reach their health and fitness goals. She is driven to share her knowledge, experience, expertise and plenty of good humor to help women discover for the first time or the first time in a while how great it feels to be fitter, stronger and healthier.

“Helping my clients discover what they are capable of from a health and fitness perspective by providing 100% customised, systematic and progressive fitness programs that they can fit into their busy schedule and actually enjoy is my job. It is a privilege to be part of my clients’ health and fitness journey, celebrating their progress and supporting them every step of the way. I love what I do.”

Sophie recently gained her Senior Fitness Specialist qualification through the National Academy of Sports Medicine.

What Clients are Saying

“I couldn’t recommend her more highly—Sophie is truly an outstanding trainer and a wonderful person.

Sophie is not only highly professional but also warm, kind, and genuinely dedicated to helping her clients. I have had cervical and lumbar spine pain, and thanks to her expertise, these issues have improved significantly.

Since I have a petite frame, I didn’t want to develop overly large muscles. Sophie carefully tailored my workouts to help shape my figure, which I am so happy about. Her thoughtful and detailed approach made me feel understood and supported throughout the process.”

~Angel

"Sophie has been an incredible addition to my fitness journey. For the last nine years she has worked around my knee, shoulder, and neck issues and managed to keep me on a challenging workout routine. I have gained muscle and increased strength AND bone density. Her positive, cheerful nature keeps our workouts fun and engaging. I strongly recommend her to anyone seeking to improve their physical health and fitness.”
