12 Rounds Boxing are a membership boxing gym in Clapham Junction. We provide both small group and one to one boxing and fitness sessions for all levels of fitness and boxing experience. Run by a small team of expert boxing coaches, who are not only incredibly passionate about boxing and fitness but also in helping people lead happier, healthier and more fulfilled lives. After discovering both the physical and mental benefits of boxing themselves, the 12 Rounds Team believe that this is not just a workout but an amazing way to build confidence and self esteem AND to manage stress.
We believe fitness should be fun, focused and supported. Not only will our sessions build your fitness and challenge you but they are always fun and interactive.
At 12 Rounds we believe that support and teamwork are the key to staying motivated and sustaining results. Our aim is to create a boxing community where our members feel valued and connected and part of our expanding boxing family. 12 Rounds Boxing is not just a place to workout but somewhere to feel strong, confident and happy and to grow into the best version of yourself
How we work
Our aim is to make the amazing benefits of boxing accessible to everyone from complete beginners to serious fighters looking to get in the ring. We even provide childcare to allow stay at home parents to get fit at our morning boxing fitness sessions. It is important to us that everyone learns the basics in a structured and secure environment so completion of the boxing fundamentals course is essential for those new to boxing before progressing to our more advanced membership programmes
12 Rounds Boxing is a membership gym only. All those new to boxing will need to complete our Boxing Fundamentals Programme before signing up to the membership. If you have experience you will be required to attend an assessment where we will direct you to the correct technique class.
We offer childcare on Monday, Wednesday & Friday for all sessions that run between 9:30 – 11:30am. If you require childcare, please email us on email@example.com.

As someone who has never been very ‘sporty’ I have always found keeping in shape a bit of a chore, with the result that I often neglected it a bit. However since I started coming to 12 Rounds Boxing Classes with Kat I have really discovered a side of myself I didn’t know about.
Practising boxing technique is very hard work, but extremely good fun. Over the last few months I have felt my fitness improve to a level that I have never managed after years slogging on the treadmill. I am also very pleased to note that I am looking a lot more toned all over – it is really a full body workout. I have finally found a form of exercise that I actually look forward to doing!Rachel Watson
I started boxing because it’s such an intense form of exercise and I like to get the most from my time in the gym. 12 Rounds seemed like a good place to learn because I liked the social atmosphere at the gym and because John actually boxes himself, so I had a lot of faith in his advice.
I’ve noticed a lot of improvement from the PT sessions with John because John picks up on a lot of things to be improved technically; he’s also very good at pushing you to the max. and that really helps with your fitness and mental preparation for a fight. Training at 12 Rounds is tougher than gyms like Fitness First and that means you come away feeling better at the end of any session and you feel more prepared.Brian Lavery
I first decided to go to 12 rounds as an alternative to a regular gym, as somewhere to keep fit, learn a new skill and then be able to apply that skill.
I was impressed about the inclusive nature of the gymn it’s open to everyone of all ages, fitness and skill level. Which makes for a friendly and encouraging environment. Also with small class sizes you don’t get lost in a crowd and you get individual attention from each session.
If like myself you have some goals in mind what ever they may be I recommend one on one PT is available which is what I have been doing with John Bryson. The main benefits are a tailored approach to your strengths and weakness so that you are able to get the most out of yourself and the session and the flexibility to fit around other time commitments.
I’m really happy with the results so far with the combination of class training and PT sessions I’m feeling fitter then I have been in a long time as well as more confident in and out of the gym.
I can’t say quite how much I love training with Kat. Never before have I enjoyed exercise as much as I do these classes and I am now a complete addict. The classes are challenging, varied and fun.
The results you will see in terms of your fitness, strength, weight loss, and changes to your body shape are quicker than other forms of exercise and a real incentive to keep going.
The classes are also a fantastic way of dealing with stress. I really recommend giving it a go – you won’t regret it!Ali Key
