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 has loved his experience at Cosens MMA. Coach Mulaney sets reasonable expectations and holds the kids to the consequences. My son is learning how to hold still and listen to instructions, he loves saying positive affirmations and really likes the homework assignments!

★★★★★ — Keri, Apr 2022

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.

★★★★★ — Eric, Oct 2025

My 12 year old son has been going to Cosens Grand Blanc for a few month now and loves it. He was dealing with anxiety, and self confidence issues. I thought this would be a nice idea to help him deal with these issues. He has taken this in like a sponge.

★★★★★ — Tom, Dec 2023

Your first kickboxing class at Cosens Martial Arts Grand Blanc LLC

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.
