Small group training vs. the alternatives
Why AKTIV's hybrid model gives you the best of both worlds.
vs. Regular gym
At a regular gym you receive a standard plan and train alone. No one corrects your technique, no personalised programming, no lifestyle support.
vs. 1-on-1 personal trainer
Classic PT costs €60–€150 per hour. For 2 sessions per week that's €500–€1,200/month. With AKTIV you pay €275–€340/month — for unlimited training.
vs. Large group classes
In a group class of 10–20 people your coach cannot adjust to your specific needs. At AKTIV max 10 people means you always get personal attention.
✓ The AKTIV hybrid model
Your own personalised program + a coach always present + max 10 people + lifestyle coaching + unlimited training. All for €275–€340/month.

Client Reviews

Real experiences from our clients
Aktiv Gym is the ideal place for me to train. The coaches provide truly tailored training: their schedules align perfectly with my capacity and goals. Thanks to their targeted guidance, I have already achieved great personal milestones without injury. A top gym for anyone looking to train effectively in a pleasant environment!
I started at this gym in 2021 with a heavy heart, saying, 'I'm actually not that athletic.' Fortunately, there was my coach Shaun, who made everything achievable and sufficiently challenging with a customized workout plan. And look, we are already five years further along! AKTIVGym is a safe haven for anyone who wants to work on their well-being at their own level. I am eternally grateful to my top coach for the life-changing support over the past few years, in good times and bad. ;) Also, a big shout-out to coaches Thijs and Andy who are always ready for support, tips, or a good joke. :)
They are all top coaches who know how to approach your guidance. You receive individual guidance from your personal coach and have the freedom to choose when you come to train. Personally, I felt that my strength and endurance, in particular, were declining in my daily life. After six months, I can confirm that I can do much more again without getting exhausted quickly and have more energy. Aktiv Gym is highly recommended.
Participating in sports with the doctor made me realize the great importance of staying active and continuing to train all muscles to get and maintain the body in good condition, which was explicitly emphasized by the coaches; it was therefore a very cool and educational initiative.
I had a very good experience at Sporten bij de Dokter at Aktiv Gym. The coaches and doctor were very professional, patient, and friendly; they helped me push my limits and do more exercises than I thought were possible. Ana
Just retired and looking for something to keep me active. What I found at Aktiv Gym was a revelation. That exercise can be a pleasure is something I never would have dared to imagine. Exercising alongside other participants, yet at my own pace, with an unprecedented array of equipment and possibilities. Thijs, thank you... for feeding my curiosity and hunger for knowledge, for helping me get to know my body, for the surprising multitude of exercises that keep things exciting and challenging, for your professional guidance, for sharing your passion. I cycle home every time feeling proud and cheerful, my body a little tired but satisfied. My mind nourished by conversations that go beyond small talk. Little chats or sentences, a vision, a thought... they mirror my view of life. A black hole when you retire 🤔🤔 Not if you join Aktiv Gym... For me, a light bulb just went on 👍👍👍
I am 62 and have been completely inactive for a long time due to illness: fitness 0, muscles ----- fat ++++. After my first rehabilitation at a clinic, I started at Aktiv 4 months ago. I never dared to think I would achieve this progress. My weight loss is noticeable! I feel fitter, stronger, and above all, I have regained confidence in my body and in myself. Despite a fall resulting in two bruised, unusable knees, a foot operation, and a completely blocked back during those 4 months, I have always been able to keep exercising. The custom-designed exercise plans and coaches who really know what they are doing make everything possible 🤗 Highly recommended! And worth every euro! And it's a friendly place too, so.... you'd have to be crazy not to start here 😅
Why AKTIV Gym? That’s the question most people ask—and I asked the same thing. I had never been to a gym before, and honestly, I was skeptical at first. But from day one, I felt welcome and even though I don’t speak the language perfectly. I joined because of my back issues. Before AKTIV Gym, I felt weak and had constant lower back pain. Now, here I am, stronger than I’ve ever been in the last six months of my life. The coaches are very approachable and always there to guide you every step of the way. The programs they create, the personal attention, and the helpful tips they give make a huge difference. On difficult or heavy days, they take the time to listen and support you and not just physically but mentally too. They motivate you to do more than you think you’re capable of. I have no regrets about joining. I truly enjoy every training session. I have a lot of respect for the coaches, they put real passion into helping me become the best version of myself ♥️ If you want to get stronger and become the best version of yourself, this is the place to be… AKTIV GYM! 💪
The best gym you could wish for. Top-notch personal guidance, high-quality members, workout plans that are immediately adjusted in case of injuries or minor “workplace mishaps,” and above all: every single one of them is a highly skilled and experienced coach. Thanks Thijs, Shaun, and Andy — absolute top-notch. Highly recommended! 💪
I got in contact with Aktiv Gym thanks to Ruth Debeuckelaere, to whom I'll always be grateful. In a very vulnerable moment of my life, she was the one who showed me the right direction towards healing and learning to love myself again. Shaun, Thijs and Andy, the coaches, we're the next gift in the journey. They taught me to enjoy training, to be disciplined, to be constant, to not be too hard on myself but remain perseverant and patient, to learn my body, my limits, to push my limits as well. But most importantly, they remained by my side accompanying me in every babysteps, while I was learning to love myself again and while i was getting to know my body again. I never imagined I'd say this (as I have never been a gym person in the past) but this gym is honestly one of my happy places, one of my safe places to go to, a place i miss when i can't go and a place i look forward going when its training day. The coaches ensure everyone is and feels safe, good and welcome, and the gym community is just as welcoming and nice. In the 2 years that i'ven been member of the gym, there hasn't been a single time that I haven't felt the warmth, support and encouragement from coaches or the community. The way they customize the training up to the last detail, adapting it when needed and always so flexible for changes or adjustments, so that you can reach your goals (whatever those might be), is the result of their commitment towards the people they train. And what makes the picture complete and round, is how familiar and open this gym is. Literally, the fact that you can go train and bring your kids with you, and everyone will be fine by it, letting the kids explore and play while you as parent train, give parents an even bigger boost. If I'd have to tell one thing to the coaches would be thank you! ♥️
I am being very well guided by my coach. He is very involved and is always ready to help. All the coaches are friendly and clearly enjoy their work.
Almost two years ago, I started at Aktiv Gym, and it has, without exaggeration, changed my life. I'd never been to a gym before and was quite insecure about it, but from day one, I felt completely at ease thanks to the friendly and relaxed atmosphere. Thijs, Andy, and Shaun, the coaches, are incredibly accessible, genuinely think along with you, and offer a completely personalized approach. You can tell they're genuinely engaged and want to help you reach your full potential. They push you without pushing you beyond your limits. Thanks to them, I've already achieved things I never thought I could. Aktiv Gym now feels like my second home and is truly my happy place. The interaction with other members is wonderful, and they organize fun activities, which makes it more than just a gym, but more of a community. I also want to emphasize that they not only guide you through your workouts but, if needed, also offer advice on things like nutrition, sleep patterns, and stress management. They're always ready to listen, no matter the situation, which really makes all the difference for me. Don't hesitate to start, just take the first step. You'll have an introductory meeting with one of the coaches, and I'm sure you'll be completely convinced afterward. For me, it was definitely one of the best choices I've ever made.
This gym works with individual design, which means: no standard programs, but training that adapts to your schedule, energy, and goals. What I particularly appreciate about AKTIV Gym is that you get what you give. The more effort and commitment you show yourself, the more you get back from the coaches in terms of guidance, feedback, and motivation. No bullshit, just great results. Highly recommended for freelancers (like myself) who want to train efficiently and thoughtfully.
Over the past months, this gym has been my second home — a place where I’ve learned proper techniques, discovered what my body is capable of, and worked on myself. Andy, Shaun, and Thijs have been incredible — patient, motivating, and supportive. They guide you, correct you, and help you push your limits safely, the personal plans based on your goals have been extremely helpful. The facility is really well equipped. AKTIV is more than a gym — it’s a community, a welcoming space, and a place where real growth happens. I’m so grateful for everything this team has helped me achieve.
Super nice place, great coaches. I am not very experienced in strength training but I was guided by the whole process, and next time I will be confident doing it the right way. 💪🏻👏🏻
I am very satisfied with my experience at Aktiv Gym. The tailored workouts and personal guidance are truly top-notch. The team of trainers is exceptionally knowledgeable and dedicated, making every session both challenging and motivating. The personal attention ensures that I achieve my fitness goals efficiently and safely. Whether you are a beginner or a seasoned athlete, you are in good hands at Aktiv. Highly recommended for anyone looking for a professional and personal fitness experience.
A fantastic atmosphere, but above all down-to-earth and professional guidance tailored to absolutely every level. From show-offs juggling kilos and weights to a petite pregnant woman like myself. Something for everyone, with the guidance you desire. So truly as their slogan says: Expect More.
This gym has changed my life. The trainers, the members, and the atmosphere are all fantastic! I can't live without it anymore :D
Best gym I have ever been to. The coaches pass on their passion for their profession to the members. They know what they are talking about and can guide you perfectly before, during, and after the workout. After the first trial class, I immediately felt welcome, and they continue to help me achieve my personal goals every day. I have never felt so physically and mentally strong. This has had a huge impact on my life; it has improved in every aspect. The best choice I could have made, and I can recommend it to everyone 200%!
It was really great training. They study the person and provide training accordingly. Great place to be at and great going if you join there.
Personal training benefits, made accessible.
The same expertise, more affordable.
