Blackbox Concept

Excellent gym with amazing personal trainers. The space is modern, spacious, clean and has all the equipment you could need. It is high quality and the people are so friendly - definitely the best gym to go to in Brussels. I couldn't recommend it more and Christos is an incredible personal trainer!

Perfect place for a great workout - very elegant, well-equipped, clean and friendly! On top of that, Christos is an amazing personal trainer! He's a great coach, observing, listening and knowing when and how to adapt the workout to each. Also, he's super fun, making you forget half the time that you're deep into your training - working out has never been such a pleasure!

Very nice place for functional trainings with great team of trainers working in a family spirit - highly recommend! Well done guys

Best fitness studio in Brussels! I go around 5 days/week, and each day has a different and super effective combination of exercises. Coaches are always there to take care of us & work out in the safest and most effective way. Their competitive advantage is the very welcoming atmosphere, their high-quality facilities, their dedication to keep the place neat and clean, their motivating music playlist and the free nutrition tips they generously share :) Ah! They are also happy to give extra exercises to the bravest ones that survive after each training session ;) - totally recommend it!

A brilliant independent gym that is spotlessly clean, well ventilated, airy spacious and well equipped. It is very friendly and welcoming and provides the perfect environment to work out in. I exercise with my truly fantastic personal trainer Milosh, he has turned my level of fitness and strength around, he knows exactly how much to push me to ensure I am always improving, and his level of care and attention is second to none. I always look forward to going to the gym, I work hard, but have fun and always enjoy an excellent coffee and chat at the end of my session! Thank guys 😊 I would absolutely recommend it.

Best gym in Brussels. Very professional coaches always there to help you and super friendly environment. You not only enjoy your workouts but also have fun.

Fantastic boutique gym that has everything you need for a great workout. Their small team is dedicated and attentive to your needs and will push you to the next level. They will make sure you learn about yourself and fitness while working out. And most importantly, they make sure you have fun when working it (and if you don't, you might be "bribed" with some delicious Greek sweets or coffee ;-)

Highly recommend this place! The personal trainers are very attentive and make you feel at home at their gym. Whatever your level or needs, you can expect a great training session with the Black Box team. Special thanks to Christos for helping me get fit :)

I've been working with their trainers on both fitness and nutrition and have seen such an amazing difference! The trainers are professional and really work with each client to achieve their fitness goals. I highly recommend Blackbox Concept!

I would definitely recommend this place ! The team is great and will give you that special attention no matter what fitness level you’re at. The overall vibe is excellent, the equipment first rate and the location super convenient. I’ve had nothing but good experiences. Special mention to Christos who introduced me to burpees and thanks to whom nothing seems impossible;-)

Perfect place to work out! Professionally trainers and super friendly staff all around.

Awesome place at a great location.
Most importantly, coaches that care, pay attention and provide high quality classes and personal follow-up.
Friendly atmosphere where you have fun and get some real work done!

Christos is the best personal trainer I have ever had. Black Box is a superbly equipped and very classy gym. Highly recommend.

I have known both gym owners for almost 3 years now and with BLACKBOX concept its the best deal in town. Considering my own experience compared to few other gyms and boxes here clients are treated with best equipment , workouts and of course with a SMILE!!!!!!!!!!!!!!!!!!!!!! Drop in and check yourself . :)

Your still not find a better place to stay fit!

I have been training with Kosty at Black Box Concept since August 2020 and have far exceeded what I thought I was capable of. Kosty has made sure that my training was able to continue even during Covid restrictions by training in the park and this has not affected my results. I would highly recommend all of the trainers at Black Box Concept as they all offer a high level of quality, professionalism and knowledge.

Amazing gym! The trainers are incredibly friendly and extremely qualified! I highly recommend this place to anyone who wants to get in shape :)

Great coaches with very good experience and wide knowledge, good people, they know what you need exactly, they know how to motivate and keep you going. Totally recomended for any beginner up to expert level.

Love this place! Well experienced coaches, friendly staff and very clean premises! Definitely to recommend!

Best place for all level training in the center of Brussels. Profesional coaches and friendly atmosphere.
