From the reviews

So after a couple months of sampling the secret sauce at High Altitude Martial Arts and I'm ready to leave my highly critical, no holds barred review. First and most importantly, the kids program is epic.

★★★★★ — Jonny, Mar 2025

Over the past 3 years, HAMA has become my kids second home and the coaches of the youth BJJ and Kickboxing program are our family. The youth and adult coaches are far more than their world class fighting resumes, they are amazing and supportive people. You will get as much out of HAMA as you are willing to invest.

★★★★★ — Mike, Feb 2024

There are levels to martial arts academies and High Altitude is just on another level. I have trained at a number of schools on the east coast and none offer what they do. Whether you are looking for a kids program, are a middle aged hobbyist like myself, an aspiring professional, or already a pro they got you covered.

★★★★★ — Morrison, Aug 2025

After training martial arts in Denver for over a decade. High altitude is one of the most legit ones. All the coaches are super experienced and knowledgeable. It’s the man in the arena. Most of the other gyms rely on systems and marketing to keep the gym running.

New to kickboxing? Start at High Altitude Martial Arts

High Altitude Martial Arts 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 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 High Altitude Martial Arts

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.
