From the reviews

Update: I've been consistently coming to class 5 days a week since my first class and feel confident updating my review. Each day I leave feeling better than I did walking in both physically and mentally. I have made friends, and grown confidence little by little.

★★★★★ — Sarah, Feb 2026

Coach Nick is an incredible Muay Thai coach and his new gym has such a welcoming vibe. He’s attentive, patient, and makes sure everyone—from total beginners to more experienced fighters—feels comfortable and supported.

★★★★★ — Christina, Sep 2025

Nick, the main instructor, is very technical and passionate. The classes are welcoming for beginners but also great for advanced and technical individuals. I’ve lost a few pounds and gained mental strength and overall confidence. This has helped me stay focused at work and overall productivity.

★★★★★ — Scott, Oct 2025

I’ve known Nick over 15 years. His passion for Muay Thai, coaching and instructing goes above and beyond for students of all skill levels. The way he breaks down techniques to the most minute detail is incredible. A great gym for everyone all around to learn this style of martial arts.

New to kickboxing? Start at Ironside Muay Thai

Ironside Muay Thai 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 class is for. A few things worth knowing before your first week. First, you don't need to be fit or coordinated to start — you get in shape by training, not before it, and coaches scale every drill to you. Second, you won't be thrown into hard sparring — reputable gyms build the basics (stance, footwork, and punches and kicks on pads and bags) first, and any contact eases in gradually under a coach's control. Third, all fitness 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 kickboxing class at Ironside Muay Thai

Nervous about walking into a kickboxing 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 — stance, footwork, and punches and kicks on pads or a heavy bag — not hard sparring. Go at your own pace and rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move and sweat in, and supportive trainers. What to bring: water, and hand wraps and gloves if you have them — many gyms lend loaner gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves and wraps (and shin guards once you start sparring). Sparring is optional and eases in gradually, once your basics 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.

Kickboxing is a contact sport. Warm up, pace yourself, 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.
