From the reviews

My 11 year old daughter and 5 year old son have both attended Ethereal Arts for just over a year now. My daughter attends the Kids Kenpo Karate class and my son, the Little Griffins, they both enjoy every minute. The tuition given by Master Frost and Sensei Mike and Jeff is excellent in my opinion.

★★★★★ — Brookes, Mar 2015

In addition to being well skilled in teaching kids in Kenpo karate, Sensei Frost and his team (including the senior back belt students who coach at times) provide a highly positive, nurturing environment in the dojo.

★★★★★ — Vasumathi, Jan 2024

Both of my kids practice at Ethereal Arts Self Defense in Stow and they love it. The after school program is fantastic - with pick up direct from school and an afternoon of activities before the evening class.

★★★★★ — Megan, Nov 2019

The classes fit my schedule and the instructors are respectful and happy to discuss accommodations for any special needs. The two week free trial gave me a chance to see if the courses, instructors, and school culture worked for me. I’ve made progress in a short time.

New to kickboxing? Start at Ethereal Arts Self Defense

Ethereal Arts Self Defense 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 Ethereal Arts Self Defense

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.
