CrossFit Coach

Marne started Crossfit in 2018 after joining Ariston to loose weight and find her zest for life again at 47!

After only 12 months, she had found it in the form of Crossfit and knew she wanted to help others do the same. Nearly 4 years to the day, Marne took her Level 1 Crossfit course and is now a part of our coaching team.

Bringing lived experience, being sedentary and overweight for 20+ years with health issues looming, Marne is now passionate about creating longevity and staying healthy and fit into her later years and wants to pass this experience onto others.
