The Undergroundgym is for everyone. And when we say everyone, we truly mean everyone. Whether you’re just starting out or have been training for years, young or old, male or female, tall or short: we tailor the program to help you achieve your goals.
Discover a unique fitness experience at Undergroundgym Arnhem, where your training is taken to the next level. Our unique location in Meijnerswijk provides an innovative and inspiring environment to become physically and mentally stronger.

Our Unique Location

Located in the picturesque Meijnerswijk, Undergroundgym combines a spacious indoor area with two generous outdoor spaces and the opportunity to train on the beach during the summer. It’s not just a gym; it’s an experience that transforms your training.

Training at Undergroundgym

We focus on bodyweight exercises, naturally building strength and endurance. Push-ups, pull-ups, squats, and lunges are just a taste of what you can expect. Each training session is a new challenge, a new opportunity to push your limits.

The Undergroundgym Experience

You don’t come here just to work out; you come for a unique fitness experience. It’s raw, it’s real, and it’s the place where you’re challenged to become the strongest version of yourself. Are you ready to experience the difference? Sign up and dive into the world of Undergroundgym Arnhem.

FREE trial class

The best way to find out if Undergroundgym is right for you is to join a free trial class!

In our gym, you train in the underground style: with old-school iron and a dose of creativity.

This is how we work with sandbags, tractor tires, and especially with your own body weight. You won’t find another gym in Arnhem with a sled track of over 70 meters and a unique outdoor area.

Even top athletes come to train at Undergroundgym in Arnhem to work on specific aspects or to prepare for major events. There’s a good chance you might run into Ajax footballer Klaas-Jan Huntelaar, Germaine de Randamie (UFC/MMA), or Boyboy Martin (kickboxing), for example.

Ik train al meer dan 10 jaar bij Underground, super gym, top begeleiding! Ben ook bij andere gyms geweest en PT maar Underground is echt de ideale plek voor mij! Leuke groepen, klein en wat groter maar veel afwisseling, respect en plezier onderling.

Lekker trainen in een rauwe omgeving met leuke trainers. Ik ging als sateprikker naar binnen, maar word nu regelmatig verward met Rico Verhoeven. 💪💪💪

Kickboksen op een te gekke locatie in een ongedwongen, informele en sportieve sfeer. Goeie adviezen en ontzettend prettige begeleiding.
