- 2008 started in GeorginaHome town, home grown. Coach Jones grew up in Georgina, taught in Toronto, London and started teaching a little in Georgina back in ‘08. He could have opened a gym anywhere but In Aug 2011 his World Famous trainer, manager & friend Shawn Tompkins died (37) and It was at Shawn’s funeral he inspired to open a gym in his home town to try and create the same positive impact on the community he grew up in that Shawn had on him and so many others.
- 3,500+ ft²Georgina’s largest combat sports facility. Wall-to-wall mats across two mat spaces, so more than one class runs at a time. Boxing ring, heavy bags, treadmill, machines and weights — the space and the equipment you actually need.
- BJJ Black Belts
& Muay Thai Kru'sTwo arts, both at world level. Our head instructor, the only one around to have fought his way onto Team Canada and medalled at the World Championships in both Striking (Spain, ’06) and Grappling (California, ’16) & he’s not the only Black Belt on the floor.

Parents Looking for Care
Before & After School Program plus MUCH MORE throughout the year:
PA Days, Summer Camp, Christmas holidays, March Break, birthday parties, special events and more.
Every single person here started as a beginner.
Nearly every adult who walks in says a version of the same thing — I need to get in shape first, I’m too old, I’ll get beaten up, you have to start as a kid. None of it is true here. Our Combat Core program is built for beginners to learn the core techniques, get in better shape and healthier, drilling with other beginners. Sparring is a choice and comes later, if you choose it. We’ve built a strong culture over the years where we work as a team and it feels like a family — welcoming to beginners and we want you to excel.
Book your first free class More for adultsWhy Rumble
We were the first gym of our kind here, and we’re still here (trust). Nobody else around here teaches both arts at this level — world-level striking and world-level grappling under one roof. Years of results, and athletes built from scratch onto Team Canada in both striking and grappling, and into the pro ranks. That’s not the reason to train here, but it’s what eighteen years of doing this properly looks like.
Book your first free classTwo arts, both at world level
Most coaches are a striker or a grappler. Our head instructor is both — he fought his way onto the Canadian national team in each, and has represented Canada around the world in both.
- 2nd-degree BJJ black belt, certified by the IBJJF — the sport’s governing body.
- Certified Muay Thai Kru under Master Toddy of Thailand, whose five decades of coaching have produced more than forty world champions, and who trained Gina Carano, Randy Couture and Tito Ortiz.
- Multiple black belts teaching on the floor.
Two free weeks. Here's how it works.
Not one class. Not a week. Fourteen days of every class on the timetable, so you can find out what you actually like.
01Pick a class
Choose a program and a day on the booking page. It takes about a minute. If you're not sure which program, pick anything beginner-friendly and we'll steer you on the day.
02Show up in comfy clothes
Shorts or leggings and a t-shirt. No shoes on the mats (socks are fine if you prefer). We have loaner gear for your first sessions, so don't buy anything yet.
03Train for two weeks
Come to as many classes as you want across BJJ, Muay Thai, boxing and more. At the end, if it's your gym, we'll find the membership that fits. If it isn't, no hard feelings.
