Got 0 experience, joining was super easy, I was provided with all the necessary equipment for my first group lesson. I don't speak Dutch - that's also not an issue: Tony & Danielle repeats all the important stuff in English, even if I'm the only non-Dutch-speaking person in a class. Group lessons are a superb workout. Doing some boring or personally-hated exercises, that I would never do on my own, never been so engaging & rewarding. It's the only thing that makes me wake up at 8am on Sundays & I'm looking forward for the next session the moment I step out of the gym. Would recommend to anyone.

Took a trial lesson at 4th gym in January and was immediately sold. I immediately canceled my gym membership and started training with Tony. Benefits of Kickboxing at 4th Gym are: - The duration of a group lesson is only 1 hour, so even with a busy schedule you can be done in no time. - you are more motivated because you are working in a group, so you cannot or do not simply stop. - Tony is a good trainer who deals very well with people and gives feedback in a nice way. - atmosphere is very relaxed, different types of people train and everyone can be themselves. - I lost more weight in 1.5 months than in the 3 years I trained at the gym. - At 4th Gym you also work on your fitness, now I can jog outside for 30-40 minutes without difficulty. Before this I trained at a gym, and with difficulty I managed to train 3 times a week. Since I started training at 4th Gym, I have been training at least 3 and sometimes 4 times a week. Sometimes you don't feel like a workout, you're more likely to skip it at a gym than here. If you want to train in a cozy and educational gym, then 4th Gym is the place for you. Even if you have a busy schedule, there are plenty of times during the week, on weekends, in the morning and evening. Tony is a top teacher, a real asset to Ijburg and surrounding areas.

Fantastic. I went for concussion recovery and tried everything until Tony crossed my path. He has a perfect sense of what you can do and even if things aren't going well, with his positive vibe he will bring you back to your positivity! Now completely healed from my concussion after 11 lessons. Cozy atmosphere and nice people.

Very nice gym. 💪🏼 Trainers take time to explain the techniques and make sure the training is entertaining but at the same time a high pace. Pleasant for expats, since trainers speak both English and Dutch. Nice and friendly people come to practices, groups are small, so even as a beginner, you feel part of the group. 🥊 Definitely recommend.

The nicest gym in IJburg and the surrounding area. The lessons are very accessible for both beginners and advanced students due to the range of different lessons offered. Due to the range of different trainers and training courses, every training session is different. Furthermore, it is a super nice gym with a nice atmosphere. In recent years I have trained at various gyms through One fit, after training here a few times it was so much fun that I stayed there. All trainers take the time to explain the lessons and technique to you so that it is easy to master. 4th Gym ensures that you start exercising again because it is fun and not because you have to. Tony is also very friendly and helpful and creates a good atmosphere at 4th Gym.

Awesome place. Amazing coaches. Went for a trial class and now I cant stop going there. Soon I will become new kick-boxing champion!

Absolutely love that place! Whole body workouts at a high pace,patient and ultra friendly toptrainers taking their to explain techniques to total amateurs like me,while giving a great amount of variety exercises. Tony & Danielle, hartelijk bedankt!

Owner is so sweet and involved, wow!

You know how it is, you register for a gym and you're enthusiastic for the first month, but then you're stuck with a subscription that you don't use at all. This happened to me very often because I didn't like sports. I have been coming to 4th gym since June 2019 and thanks to Tony I can no longer imagine my life without sports. I am extremely grateful to him for this. Tony is friendly, helpful, experienced and teaches with passion. 4th gym has literally become my 2nd home where I always enjoy going to this day. And Tony can make delicious coffee. After a boxing lesson you always get a cup of coffee :)

(Translated by Google) Tony is a very experienced trainer who helped me a lot during my match preparation. Thank you for all that you have learned over the years in the field of kickboxing. (Original) Tony is een zeer ervaren trainer die mij vaak heeft geholpen bij mijn wedstrijdvoorbereiding. Dankjewel voor alles wat je me in de jaren heb geleerd op het gebied van kickboksen.

(Translated by Google) I have now participated in a number of group lessons that I enjoyed. There is a very nice atmosphere and nice active lessons are given. Good instructions during the lesson (I follow technical lessons) and the right encouragement to get the most out of myself. To give my technique an extra boost, I have had a number of personal training sessions. My technique is leaping forward! Super happy with it. I go "not because I have to work out" but with great pleasure I go mentally free of all daily hassle and go home satisfied and satisfied - a happy person ... Thanks Tony and team! (Original) Inmiddels een aantal groepslessen mee gedaan die mij goed bevallen zijn. Er hangt een erg gezellige sfeer en er worden lekkere actieve lessen gegeven. Goede aanwijzingen tijdens de les (ik volg techniek les) en juiste aanmoediging om het uiterste uit mezelf te halen. Om mijn techniek een extra boost te geven, heb ik een aantal personal trainingen gehad. Mijn techniek gaat met sprongen vooruit! Superblij mee. Ik ga ‘niet omdat ik moet sporten’ maar met veel plezier heen, kom mentaal even helemaal los van alle dagelijkse rompslomp en ga tevreden en voldaan naar huis – een gelukkig mens… Thanks Tony en team!

Nu al een paar jaar een zeer tevereden lid van 4th gym op IJburg. Vanaf het eerste moment vriendelijk en behulpzaam ontvangen door eigenaar Tony en zijn trainers/trainsters. Wat ik mooi vind aan 4th gym is dat het heel toegankelijk is voor iedereen, dus zowel voor de fantieke als wel de minder getrainde kickbokser. Zelfs in groepstrainingen krijg je persoonlijke aandacht van ze. Daarnaast ben je altijd welkom om langs te komen voor een lekker kopje koffie of na de training in de ‘huiskamer’ van 4th gym nog even na te praten met de leden of trainers. Een echte aanrader voor iedereen!

Deze sportschool heeft alles wat een (kickboks) dojo nodig heeft, met Tony als eigenaar / trainer. Hij zal alles binnen zijn mogelijkheden doen om jou te motiveren, nog los van zijn kunde als ervaren kickbokser (daadwerkelijk in de ring gestaan) echt een topgozer. Zeer kundige trainers die je naar een ‘next level’ brengen. Bokszak training, sparren, hit training en uiteraard personal training. Bovendien kunnen kinderen vanaf 7 jaar kun je bij Tony al terecht Dit allemaal in een supergoede relaxte sfeer, waar iedereen terecht kan - van brandweerman t/m topmanagers Einde training gezellig samen een bakkie koffie/ thee drinken. Tevens een goede fysiotherapeut ter beschikking. Vijf sterren dik verdiend!! Kom zelf voor een proef les!

Nice gym. Lots of diversity in the group lessons. My son now also plays sports there and always comes home very enthusiastic.

(Translated by Google) Excellent trainer! Thanks for all private training Tony. (Original) Uitstekende trainer! Bedankt voor alle privé trainingen Tony.

(Translated by Google) Super nice boxing school, good atmosphere and vibe. Nice trainers and trainers. Apart from having fun, especially very hard and fanatical training with each other. Highly recommended! (Original) Super fijne boxschool, goede sfeer en vibe. Leuke trainers en trainsters. Los van gezellig vooral erg hard en fanatiek trainen met elkaar. Echt een aanrader!

(Translated by Google) I am a big kickboxing fan. I received personal training sessions from my girlfriend for my birthday. Tony is a very good trainer. Teach you the technique fantastic. Really recommended! (Original) Ik ben een groot kickboks fan. Van mijn vriendin voor mijn verjaardag personal training sessies gekregen. Tony is een zeer goede trainer.

(Translated by Google) Very nice school, accessible to everyone. The atmosphere is very pleasant, making it fun to train for every level. (Original) Zeer leuke school, voor iedereen toegankelijk. De sfeer is enorm gezellig, waardoor het voor elk niveau leuk is om te trainen.

(Translated by Google) Positive and inspiring environment, super friendly, personal and involved trainers/coaches.

(Original) Positieve en inspirerende omgeving, super vriendelijke, persoonlijke en betrokken trainers/coaches. Maakt van werken aan een fysieke en mentale gezondheid een feestje door uitdaging, lef en ongekend veel fijne energie!

(Translated by Google) Tony is a top trainer! Knows how to make kickboxing accessible outside the ring. He makes sure that I have a full body training without blowing myself up. Good combination between technology, power and speed, with the necessary humor in between. The result is good after 6 training sessions: fitter, tighter, more flexible and faster! (Original) Tony is een toptrainer! Weet kickboksen toegankelijk te maken buiten de ring. Hij zorgt dat ik een full body training heb, zonder dat ik mezelf opblaas. Goeie combinatie tussen techniek, kracht en snelheid, met de nodige humor tussendoor. Resultaat is na 6 trainingen al goed: fitter, strakker, leniger en sneller!

Super nice boxing school! Just over a year ago with 0.0 experience, I started taking some private lessons with Tony together with my wife and we were immediately hooked. By the way, it is highly recommended to take a few private lessons to learn the basics. Then you are immediately up to speed for the other group training. Very good atmosphere and, above all, very good and professional guidance. If we could we would go every day! It's also nice that there is a physio who can help if you ever pedal a little too enthusiastically :) Recommended!

I joined 4th Gym with absolutely no experience during the middle of a heavy burn out. It was the best therapy and helped with my recovery. Tony and Danielle's patience and compassion make this a very special place to be. Classes are always fun and engaging, you don't need to be fit, you don't need to be an expert and you certainly don't need to be young. Amazing value for money, a place where you make friends and Tony will even make you coffee ;) The best community on Ijburg, and great for expats. Join just one lesson and you will never look back. 🥊❤

I have been training at 4th Gym since September 2022 and wouldn't want it any other way. It is an accessible kickboxing school with something for everyone. You can schedule yourself for group lessons every day via a handy app. The group lessons are ideal for punching bag training, technique training, kickboxing and boxing. You can also go for High Intensity training, very nice…. Tony and the other trainers are super experienced and always add a social and professional touch to the training sessions. There is a lot of personal attention in a pleasant way. There are group lessons for young and old! You can also go for Personal Training. Tony's Pad Drills Training is legendary! In short, highly recommended and a great asset to IJburg and the surrounding area.

I have been following personal kickboxing training here for a while now to reduce my PCS complaints. Things have been getting better since I started. Super satisfied with the result and Tony's training!

Super nice kickboxing boutique. Always a warm welcome from Tony and the rest of the team. During the (kickboxing) lessons you will also receive the necessary guidance and direction and you will be well challenged. You quickly see growth and that is very addictive. Afterwards they always make time for a coffee and a chat. I enjoy going there.
