We recently visited Energia Martial Arts, a fast-growing martial arts gym with multiple locations in and around Nijmegen. We spoke with Tum, the passionate owner behind Energia, about why he chose Trainin together with Mollie and how this combination has become an essential part of running and growing his business.
Energia Martial Arts is one of the leading martial arts and combat sports gyms in the Netherlands, with six locations across Nijmegen, Arnhem, Wehl, Warnsveld and Zutphen. Members can train in a wide range of disciplines, including Brazilian Jiu-Jitsu, MMA, grappling, capoeira, wrestling and personal training.
Whether someone is just getting started or already training at a high level, Energia offers a motivating and welcoming environment for every level.
One of the biggest advantages for members is the flexibility to train at all Energia locations with a single membership. This allows members to choose the location and class schedule that best fits their lifestyle, without being limited to one gym.
Energia Martial Arts places a strong focus on teamwork, personal growth and enjoyment. Both members and instructors are constantly learning through classes, seminars, competitions and team collaboration. Tum, founder and head instructor, is actively involved across all locations and personally supports the development of his students. The team also organizes its own tournaments and seminars and plays an active role in the Brazilian Jiu-Jitsu competition scene in the Netherlands and abroad.
Searching for the right gym management app
When Tum started looking for a gym management app to take Energia Martial Arts to the next level, he compared several options. In the end, he chose Trainin because of its ease of use, personal support and seamless integration with Mollie.
“What convinced me was the combination of service, clarity and easy payments. I’m not a technical person, so it really helped that Trainin supported me through every step. The app feels like our own online gym, fully adapted to our branding. Members recognize it immediately and feel comfortable using it.”
Tum knows exactly what matters for his business: energy, community, professionalism and a smooth experience for members. Through regular conversations, Trainin and Energia continue to explore how the business can be further automated and optimized.
Seamless Mollie integration for automatic payments
One of the biggest benefits for Energia Martial Arts is how easily Mollie integrates with Trainin. Tum explains:
“I was surprised by how simple it was. With one click, I connected Mollie and could manage all payments directly from the app. Members pay through iDEAL or direct debit, and everything runs automatically. I don’t have to worry about it, but I still have a clear overview. Even when someone joins halfway through the month, the correct amount is calculated automatically. That gives me a lot of peace of mind.”
The integration does not only support recurring memberships. It also makes payments for events, seminars and individual training sessions easy to manage.
“The Mollie payment terminal is ideal. Visitors who are not members can pay directly on location. Everything runs through the same system, which keeps it simple and organized.”
By combining Trainin and Mollie, Energia Martial Arts has created a reliable financial foundation: transparent, automated and easy to manage.
Personal support and future growth
For Tum, running a gym is not only about systems and efficiency. It is also about people. That is why the personal contact with Trainin makes a real difference.
“At Trainin, I’m not just a number. They know our gym, visit us and show genuine interest in what we do. That builds trust and makes the collaboration special.”
Tum looks to the future with confidence and energy. Thanks to Trainin and Mollie, he can focus on what he loves most: growing his martial arts community, inspiring members and taking Energia Martial Arts to the next level.
“With Trainin, we have found a partner that thinks along with us. This allows us to keep growing and continue taking new steps for our members and for our sport.”
At Trainin, we are proud and grateful to work with partners like Tum and Energia Martial Arts. Together, we can continue to grow.
