From the reviews

I have 4 kids, from 7 to 16 that absolutely LOVE these classes. Sifu Jason is amazing with all of them, and his assistants/trainees/ more advanced students that help out are great also and held to the same high standard that Jason sets.

★★★★★ — Shiloh, Nov 2019

My girls ages 12, 15, and 17 take classes with Sifu Jason. They have only been going for about a month but they have learned a ton. Jason is patient and a great teacher. He builds their confidence and makes sure they are comfortable with all the techniques. I’m looking forward to also taking lessons soon.

★★★★★ — Sarah, Mar 2019

I’m working Siu Lim Tao with them right now. I like the class and Sifu Jason. We work the form and practical application. This has been good. Update: I’ve been training here twice a week for a few years now. The school has grown and remains a great place to train. My martial arts have improved immensely.

★★★★★ — Frank, Aug 2023

I showed up today to see our grandkids for the first time at their class...Jason and the staff are absolutely incredible, kind, teaching respect, values, self defense, and anti bullying and most important confidence. This style impacts kids lives forever.

New to kickboxing? Start at Theta Combat Martial Arts

Theta Combat Martial Arts 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 Theta Combat 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.
