Whether it's your first class ever or you're returning after years away, here's why adults across Northwood and Southall make Diamond the part of their week they actually look forward to — in our words, and in theirs.
“I come away from each session feeling stronger, fitter, and more sure of myself.”
Rosie — adult student, Northwood
The vast majority of our adults had never trained before walking through the door. No fitness level, no coordination, no experience required — just a willingness to give it a go. We start at the very beginning, with you.
Build functional strength, cardiovascular fitness, core stability and stamina — the kind that shows up in everyday life, not just on a treadmill. Kickboxing burns serious calories, and it's far more fun than the gym.
Consistent training, alongside a sensible lifestyle, is a powerful and sustainable way to manage your weight — and people actually look forward to coming back. No more paying for a gym you never visit.
There's nothing quite like hitting the pads to clear your head. Training forces you to be fully present, and the endorphin rush you leave with is one of the best natural stress relievers there is.
Learn realistic, proven self-defence and build quiet, genuinely-earned confidence. You'll know how to move, how to strike, and crucially, how to stay calm and capable under pressure.
Every technique mastered is a win. Members watch their confidence grow on the mat first — then quietly in the office, in social situations, and in every other corner of their lives.
Every 60-minute session is structured the same balanced way — scaled to your level, so you always know where you are and what comes next.
Mobility and movement prep to get you ready to train.
New skills broken down step by step — at your pace.
High-energy rounds to embed technique under work.
Strength, core and cardio tailored to your level.
Stretch and recovery — leave loose, relaxed and refreshed.

Our adult members are real people with real lives — parents, professionals, complete beginners and returning martial artists. What unites them is a room with no ego, no judgement and no one left behind. Coaches who know their stuff push you that little bit further each week, because they've built an atmosphere where every class is a pleasure to be part of.
Classes run in both Northwood and Southall, with members joining from Pinner, Eastcote, Ruislip, Hayes, Hanwell and beyond. If you've been telling yourself you'll start someday — someday starts with one free trial.
“Signing up to the adult classes in Northwood is genuinely one of the best decisions I've made. Every session is challenging but good fun, and they're set up to suit absolutely anyone — whether you're stepping onto the mats for the first time or you've trained before.”

“At first I felt shy, and would hold back in my shell — but after over a year of training, my self-confidence has grown so much. I now feel calm and capable when facing difficult situations, rather than anxious or unsure. We learn practical, realistic self-defence.”
Parent & Adult Student — Northwood
“I have seen continual tangible progress in my own journey. As well as technique, he frequently delves into the technical detail so I can understand the what and the why. He's personally invested in the success of those he trains.”
Adult Student & Parent — Northwood
“The coaching across the entire team is incredibly well organised, engaging, and delivered by experienced coaches. I was thrilled when Sam started the adult classes, so I could join in on all the fun and, most importantly, learn how to defend myself from the kids!”
Parent & Adult Student — Southall
Completely free, no commitment, no pressure — just turn up and give it a go.
