From the reviews

Where do I start?! We home school our kids, we travel a lot with work. We are used to being outliers every where We go. It can be challenging moving state to state, sometimes country to country. One thing that is constant in our travels, is the friends we have found in Jiu Jitsu.

★★★★★ — Nathan, Nov 2019

Been training here for about 2.5 years, and I can hands down say you will not find a better place for the services they offer. Curriculum is fresh, innovative, and open to personal adaptation. Lots of class options, from morning to evening and weekend.

★★★★★ — Jason, Nov 2018

6/16/14 Update I've been taking my ten year old son to Catalyst for ten months now. I always watch the training. This school continues to impress and exceed my expectations. Yes it is a large, new and clean facility, but that is a small part of the draw. It's the people.

★★★★★ — Thomas, Jun 2014

Catalyst is awesome! I have been practicing Jiu Jitsu at Catalyst for a couple of months now and it has been amazing. Professor Todd and all the coaches are very knowledgeable and great teachers. Everyone has been very welcoming to me.

★★★★★ — Jesse, Aug 2021

New to muay thai? Start at Catalyst Jiu Jitsu - Windsor

Catalyst Jiu Jitsu - Windsor comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never thrown a punch or a kick, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit to start — you get in shape by training, not before it, and coaches scale the conditioning to you. Second, you won't be thrown into sparring — reputable gyms build fundamentals (stance, footwork, and the basic strikes of the "art of eight limbs") for weeks before any contact, and sparring stays optional. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first muay thai class at Catalyst Jiu Jitsu - Windsor

Nervous about walking into a muay thai gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

Muay thai is a contact sport. Ease in, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
