I have used Aldgate and Paddington 12x3 Gyms and the standard of classes is fantastic. I used the gym last year as I trained for my first fight and have kept going ever since. Whether your training for a fight, getting in shape or want kick arse cardio this is a great place to go. More...

Great boxing club with great location. Clean and cosy. It's very comfortable to train here because numbers of slots are limited per session. Very functional web site where it's easy to pay, book and cancel you training. Very friendly and professional personal and trainers. Different kinds of trainings available both personal and group (Gloves On). It's definitely worth it go and train. More...

I always considered myself very fit - I was ignoring the signs of expanding waistline and changes in shirt sizes, and living on past fitness glories. It happens to all of us at some point: whether it's work or having a family, we just become content with life and that can lead to inactivity.I started to use 12x3 Boxing to help me get back to those glory days, and because I needed some inspiration with training - too much of the same thing wasn't getting me anywhere. All the trainers (in particular Nat who I train with) & staff at 12x3 are superb and offer lots of encouragement - the training sessions are great, "Train Hard, Fight Easy".....Thanks to 12x3, I am now back to fitness levels I thought I would never see again! 12x3 is much more than getting a sweat on!Its not every day you get the chance to bump into one of your hero's from your home town....

I took up the option of the 7 day unlimited trial and will be joining as a full time member because of it!! I booked on sessions with as many different trainers as I could fit in within the 7 days and each trainer was quality. All offered something completely different which made each class enjoyable and physically demanding. Everyone was friendly and welcoming and there was a real good atmosphere across both gyms. If you are looking to get fit and improve your boxing skills this is the place to go. More...

As someone who is older and looking to stay fit, 12x3 has been an amazing find. The combination of real boxing classes and fitness make it ideal for people who want to get back in shape or improve upon from where they currently are. The staff is super and the value for money is outstanding when compared to the many choices now present in London. More...

I've been going to 12x3 Aldgate for about 6 months now, and can safely say it's the best gym experience I've had (i'm in my thirties). It's a serious workout; i've never left feeling anything other than exhausted and elated. It's technical; they genuinely teach you to box, in a way that's authentic but also simple enough to be rewarding, or more complex if you're more advanced.It's intimate; class sizes are now much smaller, so you get all the attention you need. Above all though, it's just a good place to hang out; the coaches and reception team are a great bunch of people. The right balance of tough and nice. I travel an hour across town several times a week for this. No guts no glory, right? ;) More...

12x3 Boxing Gym is amazing. I currently attend the one in Paddington on a weekly basis and find it to be both challenging and enjoyable. The staff are extremely friendly and the trainers are both motivating and helpful. From a pricing perspective, 12x3 are extremely competitive and regularly have offers on their classes. If you are new to boxing, I would recommend you give this place a try. More...

Love this place, boxing is a great way to get fit and 12x3 lets you feel a little bit like Rocky Balboa. Adrien!! The coaches are all extremely professional, they keep you focused whilst making you feel welcome.

Very good gym, my endurance has clearly improved over the past year. Sparring is good here too, not only the coaches are good, but also the people attending - seems like people genuinely try to learn and not just whack each other for the heck of it. You will get what you want out of this gym - either hardcore conditioning, body sparring or full sparring, the variety of classes is great. More...

Highly recommend these guys, I'm hooked. After a long break from any form of fitness and trying multiple other classes, I stumbled upon 12x3. I've been going for a month now and can't get enough of it. The facility itself is at a great location and extremely well-maintained. Trainers are former and current boxing champions which is inspiring irrespective of whether you're there to train competitively or using boxing as a vehicle to stay fit + they're incredibly patient and encouraging with beginners like me. Such a fantastic work out each time and most importantly, great fun! More...

A great boxing gym that welcomes people of all abilities. The workouts really put you through your paces and you get to practise one on one with other people in the class so it gets you to socialise with your fellow boxers which is great, as well as practising bag work or HIIT circuits. The trainers also dedicate enough time to correct you each individually on your technique and are easy going and approachable.I love coming to 12x3 and would thoroughly recommend trying a workout there.

They never said it would be this hard to punch a bag, but they never told you how satisfying it would be. Each instructor will bring something new to your game, with a great community to encourage and drive you through those dig deep sessions. Well worth the intro sessions, and never looked back since joining. More...

I have recently joined 12x3 Boxing and my experience so far has been excellent. The facilities are great, and all the coaches I have met so far have made the initial "induction" phase of joining a new gym very easy and enjoyable (as well as being just as intensive workout as I was hoping for!)

Been going 12x3s pretty much 2 years now and still look forward to every session. This is bar none the best body workout from any sport. I always come away knowing I have been through it and the coaches let everyone take it at their own pace. Mixing up the conditioning, glove work and sparring always helps release the frustration of day to day life. All the coaches are top draw, and having all come from a boxing background either amateur or pro, they seriously know their stuff. More...

Just had my first experience at 12x3 and loved it. I loved the look and simple feel of the fully equipped boxing gym, plus the saintly lit canvas ring. Had a gloves on session with Nat especially the pad work. They have great shower facilities and offer towels and toiletries. Only issue which wasn’t an issue as it’s so humid and hot today...the shower was a tad bit cold! But I think my sweaty self needed it! I will be returning again! More...

The level of instruction from the coaches at Paddington is exceptional. I'm not a pro or amateur boxer just someone who enjoys learning the art of boxing and appreciiates the high level of experience from the trainers. No danger of bad tuition from one of the many boxercise classes that plague the industry just good honest well thought out balanced instruction from learning how to punch, how to move and how to exercise to gain the most benefit.Highly recommended More...
