From the reviews

I did my 6th birthday party for my son and we had a wonderful experience!. The instructor was awesome: professional, flexible, available, fun and strict at the same time. He was very open and flexible with our request for his birthday party.

★★★★★ — Monica, May 2014

Both of my boys have been training with Hai and his martial arts program for about a year and a half now, and the experience has been nothing short of amazing. What started as a way to channel their energy and pick up some basic self-defense skills has turned into so much more.

★★★★★ — Lindsey, May 2025

As parents we just want our kiddo to feel confident in her abilities and share her talents. I honestly thought I’d be dragging her to Muay Thai, but she loves the discipline, the challenge, and the structure. She has gained a ton of confidence and toughness in just a few weeks.

★★★★★ — Alex, Aug 2025

Hai and his colleague, Ru, came to our site to lead a self defense class for women. 90 minutes of high-intensity fun and movement, confidence building and laughter. They were both very professional and kind/approachable. Definitely recommend these excellent teachers.

★★★★★ — Beth, May 2025

New to kickboxing? Start at Tran's Family Martial Arts & Fitness

Tran's Family Martial Arts & Fitness 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 Tran's Family 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.
