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.

Love 12x3! Definitely one of the best boxing gyms in London with excellent coaches and classes that focus on improving your overall fitness but also boxing technique. Feels like a community - everyone is friendly and very supportive.

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!
