From the reviews

If I could give more stars I would. This place is amazing. My 2 ADHD-C and Autistic boys have had the best summer here. They were always busy with trips and activities but they learned so much as well. Their behavior and manners improved infinitely even at home.

★★★★★ — Melinda, Aug 2024

OSA gave me the opportunity to learn how to defend myself. I have been taking Hapkido for several years and I have gained confidence in my physical abilities. The OSA instructors are all professional, caring, knowledgeable, and patient.

★★★★★ — Tonya, May 2024

Oriental Sports Academy in Manassas has truly been one of the biggest blessings for our family. Instructor Hernandez and his mom are absolute lifesavers — so loving, caring, and patient. They made my six-year-old son and eight-year-old daughter feel welcomed and right at home from day one.

★★★★★ — Vi, Nov 2025

We have been attending OSA for about a month now and we could not be happier with this martial arts program. We were on the fence on what program to choose for our 5 and 6 year old boys. We were allowed to try both TKD and Judo before choosing so our boys could choose what they preferred.

Your first taekwondo class at OSA Martial Arts-Manassas

Nervous about walking into a taekwondo school for the first time? Almost everyone is, and good instructors 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 basic stances, blocks, and kicks with a partner or on pads — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: loose athletic wear you can move in (or a dobok if you have one); you'll train barefoot on the floor. What to bring: water and a positive attitude — many schools lend a loaner dobok for a first class, so it's worth asking when you call. As you keep training you'll get your own dobok and belt, and sparring gear (mouthguard, headgear, and guards) once you begin sparring. Sparring eases in gradually, once your fundamentals and forms are solid. Arrive 10–15 minutes early to sign a waiver and meet the instructor. It gets easier fast — most people feel far more at home by their third class.

Taekwondo is a martial art and a contact sport. Ease in, listen to your instructors, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
