About us

Four friends,
one passion.

Calisthenics brought us together. At Wolfpack, we share that passion with you: training together, challenging each other and getting stronger.

Our story

Before we opened a gym together, we were four friends with the same passion: calisthenics. That shared love of the sport grew into the idea of opening a place of our own.

That became Wolfpack. A gym in Berchem where we train and coach, and pass on our experience. You won't just meet us on this page, but during your training too.

We want to share what brought us together. Whether you're working towards your first pull-up or have trained for years, you'll find people who help you, challenge you and celebrate your progress with you.

What we stand for

For us, good training goes beyond a solid programme. It's about attention to your technique, people who encourage you and progress you can be proud of. That's what you can expect at Wolfpack, every session.

  • Quality

    Every coach has years of experience. We work with progressions and don't skip steps, in our own training no more than in yours.

  • Community

    We cap Wolfpack Base at 75 members and the group classes at 10 people per class. Everyone is welcome, and we push each other to get better.

  • Results

    Your first pull-up, your first muscle-up: we turn your goal into something measurable and check in a fixed way whether you're getting closer.

The team

Oussama, Stwively, Hasanain and Nikita: the four friends behind Wolfpack and the coaches you'll meet in the gym. Each brings their own background and speciality, with the same drive to help you progress. Get to know them — and meet Lobo, our gym cat, too.
