What the
hell
is
MOX?
I fell out of love
with it. Then found
it again.
I went to sports school, surrounded by movement from an early age. And somewhere along the way, I fell completely out of love with it. The joy got replaced by pressure — to perform, to look a certain way, to be smaller. So I stepped away.
In my mid-twenties, I found it again. But this time on my own terms. I stopped chasing skinny. I started chasing strong. And everything changed — how I trained, how I ate, how I felt in my body.
That shift is where MOX came from. Because not everyone can be skinny. But everyone can be strong.
I work mainly with women on strength training and nutrition — because strength isn’t just a fitness goal. It’s one of the most important things you can invest in as you get older, for your health, your energy, and how you feel every day.

What MOX believes.
Strength over shrinking
The goal is never to be smaller. It’s to be stronger, more capable, and more confident in what your body can do.
Science, not trends
Every recommendation is backed by evidence. No fads, no detoxes, no miracle protocols — just what actually works.
Sustainable, not perfect
Fitness that you can keep doing for the rest of your life beats any extreme plan that lasts six weeks. Progress over perfection, always.
Fitness and nutrition should be fun — and make you feel good.— Marie, MOX Fitness · Reykjavík
