Growing up in South Africa, Marnus competed at a national level in track and field throughout high school and college. Through his athletics training, Marnus discovered a love for lifting weights – this, combined with his competitive nature, made CrossFit a natural fit, first as an athlete and later as a coach.


Marnus is passionate about helping people improve their way of life, and is known for rewarding clients’ hard work by telling them how “… fan-TASTIC” their performance was.

Marnus is addicted to old school rock ‘n roll, coffee, and power naps. His vertical stature makes for highly comical burpees.
