The Heart of Undergroundgym: Meet our dynamic team!

A gym is so much more than the equipment, the location, or even the classes offered. The beating heart of any fitness facility is its team.

At Undergroundgym, we’re fortunate to have a team of passionate, knowledgeable, and dedicated trainers who help everyone, from beginners to advanced, reach their goals. Let’s take a look at the stars of our team!

Ben: The Power Behind Undergroundgym

As the owner of the gym, Ben is much more than just the face of Undergroundgym. With experience in competitive kickboxing and training world-class fighters like Boy-Boy Martin and UFC champion Germaine de Randamie, Ben brings a wealth of knowledge and experience to the mat.
Whether you’re interested in strongmen workouts, leg day, or technique and sparring training for kickboxing, Ben is your go-to trainer.

Amber: Strength and Female Power

As a specialist in Olympic weightlifting, Amber is living proof that strength knows no gender. Besides her weightlifting, Amber is also the driving force behind the Women only Booty core training, focusing on the abdomen, buttocks, and legs.
For expectant mothers, she helps you stay active as long and responsibly as possible and get back on track after childbirth.

With regular participation in competitions like ‘Strongest Woman of the Netherlands,’ she is the perfect trainer for women who want to increase their strength.

But remember, at Undergroundgym, it’s not all about training. Our trainers are also there for a good chat, advice, or even a joke in between.

Because fitness is not only about strengthening the body but also about building a community.

Unique Gym Location: Discover Undergroundgym Arnhem in Meinerswijk

When you think of fitness, you probably picture a typical gym: four walls, fluorescent lighting, and the monotonous sound of treadmills.

But what if your training went beyond those four walls? What if your gym offered more than just machines and weights, but also a picturesque setting? That’s exactly what you’ll find at Undergroundgym Arnhem in Meinerswijk.

Always Free Parking

Say goodbye to the stress of finding a parking spot. At Undergroundgym Arnhem, parking is always free. No hassle, no extra charges, just convenience.

An Inspiring View: The Rijnkade

Enjoy a captivating view of the Rijnkade during your workout? Yes, please! The location of Undergroundgym not only provides a top environment for training but also inspiring vistas that make every squat, every lift, and every drop of sweat worthwhile.

Perfect Accessibility: Wherever You’re Coming From

Whether you’re coming from Arnhem-Noord, Arnhem-Zuid, the city center, or even a surrounding village, Undergroundgym is easily accessible. It doesn’t matter which direction you come from, the journey to our gym is always worth it.

Outdoor Training

At Undergroundgym, we don’t limit ourselves to indoor spaces. With expansive outdoor areas at both the front and back, the sky is literally the limit.
Whether you want to do pull-ups, test your strength with dips, or take on the challenge of dragging tractor tires, it’s all possible. And for the speed demons? Try sprinting in our special sandpit with the sled.

Summer Beach Workouts

And for those hot summer days? Take a trip to our beach and surrender to an intensive beach workout. Whether you’re lifting heavy stones or doing a full-body workout in the sand, you’ll appreciate the fresh air, the sun, and the proximity to the water.

Discover Undergroundgym: Where Real Strength and Fitness Begin

In a world full of gyms and fitness centers, it can be hard to find the right place that meets your specific needs. But if you’re looking for a place that’s as unique as you are, then Undergroundgym is the place for you.

Stronger and Fitter

Undergroundgym is not just any gym. Here, you truly become stronger and fitter, and that’s not just a slogan. Thanks to our professional guidance and unique workouts, we offer you the chance to push physical boundaries in ways you never thought possible.

Traditional Meets Modern

While we have traditional fitness equipment, we also encourage our members to work with the most dynamic tool they have: their own body. Bodyweight exercises like push-ups, pull-ups, and squats can work wonders for your strength, flexibility, and endurance.

Core Values: Strength and Technique

One of our key focus areas at Undergroundgym is strengthening your core. A strong core is the foundation for a healthy body, helps in preventing injuries, and improves your overall performance. And while many gyms focus on repetition after repetition, we emphasize technique. Because what’s the point of doing 50 squats if you’re not doing them correctly? A very good reason to join the gym in Arnhem, Undergroundgym.

For Beginners and Pros

Whether you’re a beginner who has never done a push-up before or an experienced athlete looking to refine your technique, we are here for you. Our team of trainers at the gym in Arnhem ensures that you achieve every goal, no matter how big or small. Deadlifts, snatches, lunges, burpees, and more; with us, you’ll learn them all in an effective and safe manner.


At Undergroundgym, the gym in Arnhem, it’s not about trends or quick fixes. It’s about real results, authentic techniques, and a community of like-minded individuals pushing each other to greater heights. Whether you want to do your first pull-up or break your PR on the deadlift, we welcome you to be part of our unique fitness family.
