From the reviews

The Rock Martial Arts has become a second family. Both of my sons have enjoyed lessons. Their team of instructors are patient, skilled, kind and reinforce respect and discipline in an age appropriate manner. I love that my kids have other trusted adults teaching them life skills outside of the martial art itself.

My family and I have been learning TKD and other martial arts skills and cardio working out since 2000. The Rock has a fantastic family atmosphere and works hard to provide positive, confidence building programs great for kids and adults.

★★★★★ — Jack, Oct 2020

Review as a parent (February 2024): My 9 year old daughter took an interest in Taekwondo, so we started looking for a school that she can join in Littleton. This search process had my daughter go through a one-week trial with three other different schools before we found The Rock.

★★★★★ — True, Jan 2026

2 20 26 Update. Joined The Rock for martial arts training myself. Great physical activity and self defense training. The staff is of the highest caliber. 10 14 24 Update. Still the best. Check out their newest self defense classes and parents night out events. We've been a part of The Rock family for over a year now.

New to kickboxing? Start at The Rock Martial Arts & Fitness

The Rock Martial Arts & Fitness 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 The Rock Martial Arts & Fitness

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.
