Jarno Bonhof
Owner / Head Coach

My name is Jarno Bonhof and I’m the owner of CrossFit Amsterdam and head of photography for the Lowlands Throwdown. I used to be a personal trainer at Special Sports Amstelveen and a former fitnessmanager of the first Health City (Toolenburg in Hoofddorp). As a personal trainer my clientele was diverse. I coached famous Dutch artists like Angela Groothuizen, Jeroen van de Boom, Ron Blaauw but I also worked with topathletes like Dutch Boxing champignon Barry Groenteman and former Miss Netherlands Sheryl Baas. Heck at one day I was even involved in the TV show "make me beautifull" where I took care of the physical training part of the program... read more

After 6 years in this business and environment I needed change! So I contacted my friend Steve Cotter (Kettlebell GURU!) who introduced me to CrossFit in New York city back in 2007. The box that made sure that CrossFit was more then love at first sight was called “The Black Box”. They made my experience more then memorable so two weeks of Manhattan sightseeing became 2 weeks of CrossFit for me. I was hooked! … and inspired! All sorts of people (marines, housewives, businessman) with the same mentality! Work Hard and get results! No mirrors, machines or wellness centre stuff, just plain, old, hard training in it’s purest form. No excuses. Just workout as it should be.

My dream, having a box of my own was born in NYC!
When everything was set to go, I knew exactly how it should be, a strong and fit community of people that are for real. People that love to train Hard and to relax Hard. That have a no-nonsense mentality, that are willing to go that extra mile, that love to workout together and have lot’s and lot’s of fun doing so, so we can share our love of our common passion CrossFit! All this combined with a creative and rough/edgy unfiltered style makes us CrossFit Amsterdam. I’m extremely proud of our strong community and our coaching staff! We’re CrossFit Amsterdam! This is our box!

Marlene Clason

Partner in Crime / Co-Owner / Coach

Marlene is not only the Co-Owner of CrossFit Amsterdam she is also a very passionate coach with a sharp eye for details! She doesn‘t miss a thing when it comes to technique. She also has the most experience in "judging" athletes for competitions, including Lowlands Throwdown. So when she "No-Reps" you, you can be sure you didn’t perform the movement well. As enthusiastic as she is, she will give you an explanation on how you can do better and move more efficient!

Next to all that she is also known as our nutrition guru!
How convenient is that!
During our training we create damage in our body. That‘s why you don’t get stronger while training. You get stronger after your training with the right amount of rest and the best nutrition. That is "where the magics happens"! Now this is exactly one of her specialties. She knows everything about a healthy diet, but unlike many other nutrition coaches she knows many super tasty recipes with healthy food.

Budster! The box Dog with a capital D. With a body weight of 65kg (143lbs) and Fran time of 2:53 he can not be ignored.
But don’t get intimidated by that, he is actually a really sweet and loving friend for many people in the box.
Buddy is a true CrossFitter. He loves being lazy, eats a loooooot of food and occasionally does a short and intense work out!
He’s friendly to everyone who comes with good intentions.
But if you’re intensions are harmful, we wish you luck...
