We’ve had such a great experience with my son’s jiu-jitsu gym. From day one, the coaches have been incredibly patient, supportive, and truly dedicated to helping each child grow not just in skills, but in confidence and discipline as well. The environment is welcoming, structured, and very positive.

URSA Academy is a great gym. The classes are good, the coaches are very knowledgeable, and everyone is very friendly. The students are engaged asking question and everyone is just looking to gain experience and get some good rolls in.

★★★★★ — Ron, Jan 2026

I love training here. I've been there a few months now. I was hesitant to go to the trial class at first because it was totally out of my comfort zone but once I got there I was hooked and signed up immediately. The coaches make me feel supported and I love the teaching style.

New to muay thai? Start at URSA Academy - Ribeiro Jiu-Jitsu Ann Arbor

URSA Academy - Ribeiro Jiu-Jitsu Ann Arbor 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 URSA Academy - Ribeiro Jiu-Jitsu Ann Arbor

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.
