Everyday people,
extraordinary results.
CrossFit Leiden is a place where busy parents, young professionals, students, expats and people who haven't worked out in years get stronger together. No judgement, no pressure. Just training and growing together.
Why CrossFit Leiden
is different
We're not a typical gym. CrossFit Leiden was founded on one simple idea: everyone should feel welcome to work out, whatever your age, fitness level or experience.
No macho culture or intimidating vibe. Here you train next to parents who come in after bedtime, expats looking for a new community and people who haven't exercised in 10 or 20 years. Everyone starts somewhere, and we'll help you on your way.
We don't just train inside the gym. We take on challenges outside the box together: HYROX events, runs, outdoor challenges and trips. The gym is the tool. The goal is that you stand stronger and more confident in life.
Over the next 10 years we'll help 4,800 people become stronger, more positive and more energetic.
Kees & Jeroen
Two friends who believe everyone should be welcome to work out. In 2015 they started CrossFit Leiden with one simple idea: a place where everyone is welcome, whatever your level or experience.
Kees grew up in a gym and discovered CrossFit in 2012. He opened Gymbox Noordwijk in 2014 and co-founded CrossFit Leiden with Jeroen in 2015. Kees lives in Katwijk aan Zee with his wife Nathalie and their two sons.
Jeroen has always been active, from football to surfing. In 2014 he chose the fitness world and coached people in Chile before returning to the Netherlands. Together with Kees he built CrossFit Leiden into a place where everyone feels at home.
“I want CrossFit Leiden to be a positive lighthouse in the city. A place where energy starts and spreads to families, businesses and the streets of Leiden. A second living room where you feel seen and where you walk out a little stronger every week than when you came in.” – Jeroen
