The coaching and community at Denver Modern Jiu-Jitsu is world class and I highly recommend any beginner to advanced practitioner of Jiu-Jitsu to take a class!

★★★★★ — Demel, Nov 2025

It took several attempts to find my ideal training environment, but THIS IS IT. Denver Modern has everything for anyone interested in jiu jitsu, muy Thai, MMA, combat sports - we have World Champion instructors (quite literally) who absolutely know the details of their technique and skill.

★★★★★ — Eyreka, Feb 2026

Dropped by Denver Modern while visiting from out of town. These guys are the real deal. The class was structured well, there was a good mix of blue, purple, and brown belts to roll with, and lots of mat space to grapple. Shout-out to Manny, Rico, and Don for being so welcoming.

New to muay thai? Start at Denver Modern Jiu Jitsu

Denver Modern Jiu Jitsu comes up as a beginner-friendly gym — noted on their own site. 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 Denver Modern Jiu Jitsu

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.
