Small-group Muay Thai & Boxing · Castle Hill
Weapon is a small-group Muay Thai and boxing gym in Castle Hill. If you've been paying for a gym you don't use, or you've tried classes where nobody knew your name, this is built for you: small, friendly, closely coached sessions where you get fit, learn to defend yourself, and actually look forward to training.
Every class included. No lock-in. Cancel before the week ends and you owe nothing more.
Sound familiar?
Nobody at a big gym notices when you stop coming. Here, the coach is expecting you, your partner needs someone to hold pads, and there's a handful of you in the room. You'll show up — and before long you'll want to.
Thirty people swinging at bags isn't coaching. In a small group, every round gets watched and every mistake gets fixed. That's how you actually get good.
An hour on the pads does what a scroll session, a wine or a walk never will. You leave with nothing left in the tank and a clear head.
Not choreography and not bravado. How to stand, move, keep your guard and stay calm under pressure — drilled until it's automatic. Quiet confidence is the goal.
No sparring in classes. No one thrown in the deep end. Intensity is set for you, not for the fittest person in the room — which a small class lets us do.
Same. This isn't a fight gym. It's a small, friendly room in Castle Hill where normal people get fit, learn a skill and look forward to Tuesday nights.
Why small works
Big gyms make money from members who don't show up. We only work if you do — so everything here is built to make you better, and make you want to come back.
Start your $10 trial weekEvery class is booked in advance and kept small, so the coach plans the session around who's actually coming. You get coached, not supervised.
We learn how you move and what you're working towards. Technique gets fixed 1:1 inside the class, not in a video you were supposed to watch.
Friendly people, zero ego, no one showing off. Training partners who notice when you're not there and are glad when you are.
What we do
Two Muay Thai nights, two boxing nights, one Saturday morning that mixes both — plus one-on-one sessions by arrangement. Every group class is small and booked in advance, and every one is included in your trial week and membership.
Kicks, knees, elbows, pads and conditioning in a small group.

Full timetable & booking →How the $10 trial week works
One free class tells you nothing. A week tells you everything — how the coaching feels, who else is in the room, and whether you're looking forward to Thursday. You're booked in exactly like a member, so you see the real thing.
Your first week is $10 and includes every class. If you love it and do nothing, it rolls into the Unlimited membership at $65/week. If it's not for you, let us know before your week is up and that's the end of it — no fees, no awkward conversation.
Pick your first class — Mon/Wed Muay Thai, Tue/Thu Boxing or Saturday morning. We'll text you to confirm.
We'll get you set up, wrap your hands and introduce you to the room before anything starts.
Try Muay Thai, try boxing, do Saturday. You're booked in like a member, so the coach plans for you.
Love it? Do nothing and your week rolls into Unlimited at $65/week. Not for you? Tell us before the week's up and that's that.

Straight answers
No — that's the point of keeping classes small. The coach is with you on every round, you're partnered with someone at your level, and nobody assumes you know anything. Most people who walk in have never thrown a punch.
No. Classes are pad work, bag work, partner drills and conditioning. There's no sparring in our group classes. You'll learn to defend yourself properly without being punched in the face to do it.
That's most of the people we want to train. You work at your pace — the coach sets the intensity for you, not for the fittest person in the room. Small classes are what make that possible.
Because classes are kept small and the coach plans each session around who's coming. Booking takes a few seconds online and means you never turn up to a full room. Members book too.
Your first week is $10 and includes every class. If you love it and do nothing, it rolls into the Unlimited membership at $65/week. If it's not for you, let us know before your week is up and that's the end of it — no fees, no awkward conversation.
Unlimited classes are $65 a week. Private + Unlimited — one private lesson a week plus every class — is $150 a week. Both are weekly memberships with no lock-in contract; just give us two weeks' notice if you need to stop.
Comfortable training clothes, a water bottle and a towel. If you don't have gloves yet, mention it when you book and we'll sort you out for your first sessions. Arrive a little early so we can get you set up and introduced.
Try both during your trial week. Boxing is hands, head movement and footwork. Muay Thai adds kicks, knees and elbows. Saturday is a mix of the two. Most people end up enjoying both.
Not yet. Every class is small enough that beginners are looked after inside the regular sessions. More classes will be added as we grow — leave your details and we'll let you know.
We're at Unit 1 / 7 Hoyle Avenue, Castle Hill NSW 2154, inside Shirudo Gym. It's a few minutes from the Castle Hill Metro and Castle Towers, with parking nearby.
