From the reviews

"This place is amazing and has been a huge help for my brother in terms of discipline and social skills. He used to be very shy and struggled to connect with other kids, but here he's found a welcoming and stimulating environment that has allowed him to grow and develop in a holistic way.

★★★★★ — Estefany, May 2025

My son started at Cosens in April of 2022. He has grown so much, physically, mentally and emotionally. He has learned self discipline and amazing character development. All of the coaches are so patient with him and always want to see him grow as a martial artist and as an individual.

★★★★★ — Amanda, Jul 2022

We've been at Cosen's for over a year now and the self discipline in my 5yr old is astronomical. The best coaching staff that interacts and knows each student on a personal level.

★★★★★ — Kristine, May 2024

Adult Student - Black Belt Program (White belt): I can't say enough about training with Cosens in Grand Blanc! I started back in the early summer, looking for some accountability when it came to staying fit, and decided to give myself a challenge: MMA.

New to taekwondo? Start at Cosens Martial Arts Grand Blanc LLC

Cosens Martial Arts Grand Blanc LLC comes up as a beginner-friendly school, going by their listing and students’ reviews. If you've never trained or set foot in a dojang, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or flexible to start — you get in shape by training, not before it, and instructors scale the intensity to you. Second, you won't be thrown into hard sparring — reputable schools build fundamentals (stances, blocks, kicks, and basic forms) for weeks, sparring eases in gradually and with gear on, and instructors keep it controlled and safe. Third, all ages and all 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 schools are happy to let you watch or try a class first, so reach out before you commit.

Your first taekwondo class at Cosens Martial Arts Grand Blanc LLC

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.
