About KB

KB Fitness was born in 1999, simply because it had to be. As our school is owned and run by women – super rare in the martial arts – we know that we have the most nurturing, welcoming martial arts classes in London.

In fact, 75% of our membership are female, which is certainly uncommon.

A couple of our newest members said this about us when they first joined:

As a direct result of the teaching teams’s gender, the men in our school are not the testosterone-fuelled, heavy-hitting types often associated with a Kickboxing school. Instead, we have created a wonderful, inclusive training space, where everybody looks out for one another. Egos are kicked out the door at KB. Most importantly, all members are free to be themselves, without discrimination of any kind.

A relaxed and welcoming group of instructors and training peers await you. We know how hard it is to step into the unknown, which is why we’re going to make you feel safe and settled as soon as you get to class. Unlike the often hostile, lonely gym experience, our team are very much hands-on;, we will know your name and care about you. As soon as we welcome you with a beaming smile, we’ll accompany you every step of the way through your martial arts career.

Kelly (KB) started training in the martial arts in 1985. In Borehamwood in 1998, Kelly (KB) decided to pass on her expertise to others. Following that, in 1999, she then launched KB Kickboxing classes in Central London. She couldn’t keep up with the demand, swiftly growing from 60 students to 760 memberships. KB Kung Fu classes were introduced in 2004 and KB Self Defence classes were born thereafter. Actually, so was KB Dance, KB Tai Chi, KB Core, KB Pilates and KB Yoga; as a result, the KB Fitness brand was born.

Nowadays, we solely offer training in the martial arts, so KB Kickboxing classes, KB Self Defence classes and KB Kung Fu classes.

Well into our 25th year of existence, we’ve weathered the lockdowns and we’re still standing strong with a loyal following of addicted students, because our classes are not just about physical arms and legs being converted into punches and kicks. Instead, our members will testify that the instructors teach on a spiritual level, to bring out the fire within you, enabling you to roar and soar in and outside of our dojo.

Our Kickboxing lessons and Self Defense lessons are popular because our intention is to teach an art form, improve our members’ confidence and fitness, at the same time as providing the forum for making new friends and having lots of fun. KB Fitness is a safe, positive and vibey environment. Wouldn’t you agree that in this day and age, having a space where you’re praised and engulfed in positivity is unique?

People are always asking, “do you know of any martial arts classes near me?” Well, the fact that our online martial arts classes can be from the comfort of your own home, as well as in person, means that we can provide the “martial arts training near me?” solution. Our members immediately sense that the ambience in our training space is rare and consequently very special – it is unusual that a martial arts school is unintimidating. Our Kickboxing classes London and self defence training are a great place to unwind, to switch off and shut out the noise. How many times a week do you currently get to do that? One of our members said:

With regards to anxiety, yes, it has helped. For me it’s mainly because it makes me focus on something else, or something specific. While the world outside is noisy and overwhelming, Kickboxing training is silent and peaceful. It gives me a sense of accomplishment when before I felt that I couldn’t really finish anything. KB has helped me believe that I can be good at something when I spent a long time believing that I couldn’t do anything right or that I was less. I have become more calm and more positive, happier. I said this before and I meant it. You have taught me to be patient and not to give up.

Our adult Kickboxing classes are simultaneously in Euston and online. Our local martial arts classes are catering to adult beginners, right through to Black Belts, but all ages are welcome to join our online martial arts training. It can be a real family affair.

People often search for ‘private martial arts training near me,’ or ‘1 on 1 Kickboxing training near me.’ Our team do not have enough time to teach private Kickboxing lessons. That’s not a problem though, as training in our martial arts courses gets the same results as martial arts private lessons for a mere fraction of the cost.

One of the benefits of learning martial arts is the fact that it is progressive. Students experience a marked and measured improvement as each month passes. One way to measure that progress is to take belts; a staged grading syllabus is highly rewarding. It’s not obligatory at KB Kickboxing though, entirely up to you. In fact, every student is free to progress at their own pace.

In the earlier stages of Kickboxing training, there is no pressure to get things absolutely ‘right’ but always encouragement and guidance to try and improve technical performance. We know you will be striving to be your best and our support will mean you can do so, engendering a tremendous sense of pride as regards to all you achieve.

Kelly (KB) is on hand on an ongoing basis via WhatsApp and email to ensure that you are happy with your technical prowess and progression. We actively encourage you to ask for her expert guidance.

There are so many things we can be doing in our spare time; we highly recommend you add training in the martial arts into the mix of your work-life balance. Despite having to step out of their comfort zone, all of our members are delighted that they took the plunge, as you’ll see in our member testimonial videos.

The profound positivity within our training space is contrary to an often hostile wider world. Everybody nurtures, encourages and praises one another, celebrating each other’s progress. Does that happen anywhere else in your life?


All of our martial arts classes are conducted by fully qualified instructors; the foundations of the classes rest securely on ancient martial arts as opposed to aerobic qualifications. 

Lineage is significant in the martial arts, with one generation passing on their knowledge to the next. Kelly (KB) was taught by 5-time world champion, Kevin Brewerton. Kelly (KB) is now assisted by a team of highly qualified, proficient instructors who she personally taught; some of them can be seen in this video.   

Kelly (KB), Dee, Jess, Beth and Frederike are looking forward to guiding you through your martial arts journey – they thrive on igniting you with a vibrant new energy. One of our members said:

The support I get from the teaching team is amazing, it invigorates me on bad days, I feel so safe, and I leave so positively impacted…I am so glad that KB Fitness came up when I searched for ladies Kickboxing classes near me!

Your first instructor will be Dee; she can’t wait to meet you. On a Monday or Wednesday, Dee, 3rd Dan Kickboxing Black Belt and Judo Black Belt, will be teaching you your first Kickboxing class and / or self defence class, which have been prepared by our martial arts school’s Chief Instructor, Kelly Bunyan, 1st Degree Black Sash in Kung Fu and 4th Dan Black Belt in Kickboxing. The rest of the teaching team look forward to teaching you if you choose to train on a Thursday.

Our teaching team’s energy is unprecedented, very dynamic and inspiring. The team have a strong, confident presence, which enables them to motivate you, at the same time as being patient and committed to ensuring that you are satisfied with your progress. Many of our members say that our enthusiasm is infectious – are you up for becoming one of our addicted members?

Kelly (KB) said: “My passion for the martial arts runs through my veins. Often I can’t articulate through language the energy that literally erupts out of me. Instead, I rely on gesticulations and lots of strange sounds, such as, “Phwoar,” “wooarrr!” I feel so fortunate to be so passionate 37 years after I first tentatively stepped into the unknown. All I hope for, is to give to as many people as possible, what the martial arts has given me – an unprecedented boost to my mental and physical health.”
