I’ve been a student for around 6 months now in the adult classes. I have learned many Mixed Martial Arts skills and I am confident to be prepared for any situation just in case I need to use self defense. I have made many friends and I’ve created strong relationships with the coaches! Black belt training is really convenient and it’s fun to spar at your own paste. My strength and conditioning have improved so much through the time I’ve been taking classes. I would highly recommend Cosens Mixed Martial Arts for anyone.

The coaches are GREAT! We have been with Cosens MMA for over 4 years now and my son has learned SO MUCH! They teach great life skills, self defense and respect. It has been great watching my son grow to be a more confident child! Thank you for helping him find his voice!!!! 10/10 would recommend!!!

My daughter has been at Cosens for almost 2 years and was having trouble in school. Since joining Cosens, she has gained focus, self esteem, and self control. Thank you to all of the past coaches and the current coaches for everything. This girl loves karate thanks to you!!

Well organized, clean facility that teaches kids and adults respect and discipline through MMA. Highly recommend!

Awesome place to go. Coach D and coach brewer are Wonderful. Charlie the owner is super great to work with and understanding. Hands down 100 percent recommended this place.

The coaches at Cosens are awesome. I have two children who take classes there. They make the kids comfortable and build their confidence. On the first day the kids fell right into place there. They look forward to going!!

My son and I both attend Cosens MMA. The classes are fun and the ENTIRE team is amazing! I always enjoy talking with Sarah at the front desk, she always has a smile on her face. Coach Brenay is great at getting the kids attention and getting them to focus. Coach Kons is so patient with the kids and my son enjoys him as his coach. Coach Kons also teaches the adult classes. He gives us a great workout that is enjoyable and he is a wonderful teacher. This is a great place for people of all ages to gain some good life skills and to get you in shape.

Great Place to learn and make friends.

I am an SVSU student currently enrolled in the Adult black belt program at the Bay City location. Prior to enrolling I had little martial arts experience. Cosens MMA has been a great place to learn the foundations of mixed martial arts and self defense in a friendly, encouraging, team based atmosphere.

My son Kaleb is in the junior black belt club. He has only been in for a few months but he loves it. Everyone is amazing with the kids, his first couple days he was scared to join the group and would stand back abd cry because he wanted to do it so bad but was scared. They slowly worked him out into the group and now he fits right in, loves it and tells me every time he doesnt want to leave and wants to stay longer. It has helped him so much with his self confidence and hes a much happier little boy. I just wish I could afford to put my daughter in too. Thank you to all the coaches for what you do for these kids. You are truly amazing

I was looking for an organized sport for my six year old son. He was struggling in school with listening skills, focusing & following directions. To my surprise, Cosens offered two free trial classes. My son immediately took to the coach & couldnt wait to start classes. Within no time, I noticed a tremendous difference in his confidence, focus & attention span. He is making such positive strides in the classroom, is a much more helpful & enjoyable guy at home & is becoming a leader in his karate groups. I am beyond grateful for Cosens. They are not just another sports team, but a family that encourages, supports & cares for the growth of my son.

Great values taught here. Coach Brenay is great with kids. So glad to see him back at the front of my daughters class. He is always pushing them to be the best version of themselves.

Coach Brenay is awesome. Very helpful and professional and personable. My kids love going!

Karate aims to build character, improve human behavior, and cultivate modesty..cosens MMA in bay city has great atmosphere, putting out good messages.. and teaching my kid how to defend herself..but most importantly how to be responsibe, respectful, humble and strong. Coach bernae is the most passionate teacher Ive encountered for life and mixed martial arts skills. KEEP IT UP COACH!

My son started classes with Cosens 2 years ago and we couldnt be happier with our experience. While we like the physical skills he is learning, we love the focus and emphasis on life skills such as respect, kindness, hard-work and responsibility. This helps him in at school, and is a big motivator for doing chores at home. The coaches take an interest in each student personally, they know what is going on in their lives and they notice when the kids are struggling. The personal support the kids receive from someone other than a parent is invaluable. We love our Cosens coaches and staff.

My husband and I have seen great improvements with my sons listening skills and self control. This program has been a great place for my son to expel his energy in a positive way. We have seen less tantrums and frustration in him at preschool as well. The staff is great with the kids and he looks forward to class! Highly recommend!

Weve had a wonderful experience with Cosens MMA! Nearly four years now and our son and daughter love going to class every week. Coaches keep the kids interested and always find new exciting ways to teach techniques and core values. Keep up the good work!

What makes Cosens MMA better than your average martial arts school is seeing how the kids blossom into confident, strong, and determined leaders. Every lesson is tied into a valuable life skill like respect or self-discipline. The coaches are so dedicated and theres a great family vibe here. I cant say enough great things!

My daughter has been in MMA at Cosens for almost two years, and absolutely loves it! It boosts her confidence, self awareness and has helped so much in teaching her about integrity and values. The coaches have been outstanding and really put their all into each class with the kids.

We have had our son in Cosens MMA for over 3 years now. It has been one of the best decisions for our son for many reasons. I know that it has helped his confidence, has helped him socialize and surround himself with other kids that are trying to be great human beings, has taught him things that I myself as his father have been trying to teach such as what respect really means, integrity, perseverance, leadership, accountability, responsibility, self confidence, etc. They have changed coaches a few times but I believe every Coach has been a great pick and fit for the gym. We are very happy to be apart of this team.

This is the best thing I could find for my daughter. She really loves the group and the coaches make her so comfortable. The students are wonderful by making her feel welcome. I highly recommend this place.

My grandson started here about 2 months ago. Best thing that could have ever happen to him. He absolutely loves it and loves the coaches. Such a great place with great people. Thank you!

James took an interest in karate the minute he started. He liked the drills and the coaches. They work super hard at building his confidence and focus. He is determined to be the best he can and wants to show them his ability. He needs a little more help with his coordination and his stance at times, especially since he is ambidextrous, so his lead kick and rear kick changes from time to time.They have just started taking the extra time to work with him independently on the things he needs to work on and it makes me so happy, because sometimes with a bigger class size, it is hard for two coaches to get around to each individual. So taking the extra time outside of class, is really appreciated by me and says so much more for the company in my opinion. It shows the belief they have in my child, which not only encourages him, but myself also.I hope he never loses his love for karate, I have seen so many positive changes since he has started and hope that it only continues to grow. In his eyes, his karate coaches are celebrities and he respects them, but also doesnt want to let them down. Thank you for all that you do. 👏👏YOU ROCK!

After 6 short months of our daughter attending MMA at Cosens, we have seen quick benefits and results. The approach they take is holistic, innovative, and current to meet the needs of our growing kids to equip them for todays secular challenges. Each class comes with skill building and a character building lesson that will stick with these kids the rest of their life, its priceless and we are pleased with the encouraging, positive atmosphere at cosens.

**** Coach Bernay did a excellent job with our first two introduction classes, his patience and ability to see what my 9 year old son needed help with and took the time to relate to him and have him doing it correctly and did it quickly which gave him confidence. My 14 year old daughter loved being able to unload on coach holding the kick/hit pads correctly and with power and speed she never knew she had. I like the fact they get involved in the kids life as well, not just in the gym which I noticed while I was there. I signed up both kids.

My granddaughter Chloe (8), has been going to class, for 2 yrs. The improvement she has made, in her self confidence, is just amazing. From being very very shy, too now being highly motivated. Has help at home, and at school. The coachs are simply awesome, the way they work with young children. Is something they should be, very proud of.If you want your child, to have self esteem, self confidence, and self discipline. While getting taught, life lessons, team work, selflessness and self defense.I would highly recommend Cosens MMA. For your child, grandchildren, or even young to old adults.

My son has been going to Cosens gym for the past year, starting the program at 3. I have seen so much positive change over this year, he has developed confidence in himself. Also, the work on focus has been great both in and out of class. The coaches are absolutely wonderful to work with.

The coaches and staff are amazing! Great place to learn confidence and self discipline! My son has been going there for years and we love it!!! I can’t say anything bad about it!!

Absolutely love this place and so does my son! The coach works so well with the children and explains everything at the kids level so they understand. Two thumbs up!!

My son has been going here for over a year. The coaches are great, they reinforce discipline, respect, and anti-bullying. They provide great role models for children and the children learn great social skills.

My daughers (11 yrs and 8 yrs) have been attending Cosens MMA in Bay City for just over a year and we are so happy with their life skills based program. Both girls are learning important leaderships skill. We really appreciate the time the coaches take to check in with their students and to teach life skills like commitment, perserverance, respect and responsibility. It is great for them to have a safe and welcoming place to make new friends outside of school. Health and fitness are important to us, so we also love that our girls are getting excellent exercise and learning skills in endurance, strength and stamina. They come off that mat sweating! Thank you Cosens!

Weve had a great experience with Cosens MMA for a few years now. They are focused on growth of the students beyond the physical. Goal orientation, focus, and other life skills are incorporated to each class. Weve found it to be a real positive for our son.

Our daughter has been a little ninja for just about a year, and our experience has been amazing. The coaches are really great with the kids. We have seen a tremendous improvement in our daughters confidence. About a month ago, my husband started training at Cosens as well and he loves it too!

Were new to the gym but so far our experience has been amazing. My daughter is in the tiny ninjas program and has she had so much fun that she never wants to leave. The coaches and staff are helpful, patient and great with kids. They challenge and encourage the children to be their best selves. My husband and I like that the program doesnt just focus on fitness but mental focus and self-control.The sheer number of events they put on outside of classes means that when you join this gym you have a environment that welcomes the whole family with open arms.It is more expensive than other activities but our family thinks its a worthwhile investment.

The coaches really emphasize life skills! My son has gained so much self confidence and has shown more respect to his family and teachers.

We have been sending our son for nearly a year. The coaches have gone out of their way to truly make us feel like family, and we have seen tremendous growth within our son and his confidence. Thankful for this program and these coaches!

All three of my children attend Cosens MMA, ages 3, 14, and 19. Its a great place where all of my kids are getting life lessons taught to them. The coachs are great with all the kids there. If you are thinking about trying them out, I would suggest to give it a try, you wont regret it. Its also a great place for the older folks, myself included. I take fitness and self defense, great class also. Give them a try!!!!!!!

I am loving this program and my decision to sign up my son! His behavior has improved as well as listening skills and focus. He loves going to class and does get upset when he is late even though we’ve only been late once.My only complaint would be the class size is too large for the number of coaches but the coaches have added an extra class to alleviate this issue. I am still very happy with this program and plan on extending his enrollment for longer!!!

Coaching is great, my son loves the teen program. Great street smarts plus away too burn energy. Team building atmosphere and self control and confidence.

I put my son in tiny ninjas because he needed a confidence boost since he struggled with spd. The coaches have helped in so many more ways then just teaching him martial arts. He looks forward to going to class and cant wait to share things with his ninja family.

My son had private classes and then started weekly classes, this place is amazing! The coaches are so kind, caring and helpful. My son absolutely LOVES it. Its something for him to look forward too very good mentors, I absolutely recommend it to everyone I know! I love the cosens mma family! Thank you for all you do for my son!

Cosens MMA is awesome! My son has been going there for almost 3 years and I have seen so much growth in him! I would highly recommend taking your children there!!!!

Our son enjoys MMA and has grown so much since he started ....his dedication, discipline, and even has gained confidence. We appreciate all of coaches and the work they have done with him.

So very pleased with the quality of the program and the staff. 7 year old has attended for a year and a half now and is still just as excited as when he started. Mat chats teach the kids so much mentally as well as they are taught physically. Coach Greenwood and Coach Abernathy are top notch.

This is the best place, teachers are great and the kids love it. If you want something for your kid to learn and have fun I highly recommend this place

Very friendly staff and great coaches! It’s also a great support group for the kid’s. He’s progressed tremendously in the 4 months that he’s been enrolled.

Offers fantastic classes to teach you the fundamentals of how to protect yourself and loved ones in any bad situation. It has helped to build my confidence and improve my balance, listening skills, and rhythm while getting a great workout too! The instructors are some of the best teachers Ive had. Very hands on, always willing to help you, and motivate you to reach your goals! I would recommend this gym to anyone looking to enrich their skills in life whether it be setting goals, protecting yourself, or getting fit.

This is NOT what you think...its NOT training your kids to be fighters or to beat kids up! It builds character, self confidence and teaches all the characteristics lacking in the young community today! The coaches are fantastic, the facility is top notch and I couldnt be happier with the experience Ive had with my son thus far. I cant say enough about the lessons and team building done here. No better program for young folks.

I started taking 2 self defense classes back in January. I absolutely loved the classes & decided to add on to my classes at Cosens MMA because I love spending time there! I got my sister & my brother enrolled too & we all love what we do in our classes! Im so glad I choose this gym with such great staff. Theyre all willing to help out & make sure you develop an understanding of what youre learning. I highly recommend this gym if youre looking for great coaches & a great time while working out!

I came here with the intent of rounding out and expanding on my 10+ years of martial arts training with some groundwork/grappling in their Jiu-Jitsu class. I ended up also testing out their MMA class and the fit camp. I cant say enough good things about my experience thus far with this facility! The classes are well-rounded from techniques to physical workout, the coaches are knowledgeable and upbeat, and the staff overall are friendly and great to work with. You get exactly what you ask for and put into each class.Most of all, everyone here is welcoming and treats you like family. Their support and positive attitude has not only been great to walk into every evening, but watching the impact theyve had on my friends and loved ones has been more wonderful than words can describe. I have watched people regain their confidence, come out of dark places personally, and find a new support system here. I highly recommend coming in and giving this place a try!Side note: LADIES! Do *not* be intimidated to come in!! Martial arts is never just for the guys. Come and gain new skills, more confidence, and have fun with the rest of us!

The coaches are great, friendly and very personable. They are taught life lessons and how to act. Not all about the moves... They make learning fun..one of the main reasons we make the long drive 2 times a week..give them a try......

The coaches have so much patient with kids especialy the younger kids, the coaches handle things like acting out,very well,the coaches also teach kids martial arts in a way that it is understandable and fun so the kids have a easy and fun time going. thank you to cosens and their amazing coaches

I have been with Cosens for about 5 years now. I have and do train at other gyms when I am out of State. I can honestly say comparitively that no other gym lives up to my expectations. They say once youve had the best mediocre is just the rest. It is the truest statement I have heard. The coaches are specially trained by Coach Cosens. Coach Cosens has very high standards yet nobody ever is left feel like they are not good enough. You can come in dragging your feet or feeling less than, but you will always leave feeling more than. I dont know what else to say except give it a try.

We adore Cosens! The coaches are extraordinary, they have an amazing rapport with the kids and do such a great job keeping them engaged in class. My son has already been applying what hes learned in his day to day activities. Hes focused, respectful and learning a lot about self-control. The Tiny Ninjas and Little Ninja classes are great tools to achieve our parenting goals. And all while having lots of fun!

My grandson has been going to Cosens for two years now. He started with the little ninjas and worked his way up to the black belt club and also the leadership team. The staff there are wonderful. They help the children develop skills that they can use in all aspects of their life, like focusing on goals, paying attention, being respectful and learning the fundamentals of public speaking. They gain the confidence to try things they normally wouldnt do. Charlie and the rest of the coaches treat the children and parents with respect. I would recommend this program to any parent with little ones.

This is an awesome place they have great trainers! I already see a different in my child and highly recommend.

We absolutely love the programs that they offer here. All of the coaches are incredible! Coach Brenay is especially great with the kids!

My daughter is in the little ninjas program. and i have never met a more caring group of coaches. They care about the kids so much. my daughter has become more confident, less distracted and overall happier since joining. I will 100% recommend Cosens to everyone.

Been coming here for almost a year now. Great atmosphere. I love all of my teammates. The coaches are always upbeat and promoting a positive environment for everyone. If youre in the area and thinking about trying MMA, this is definitely a great place to train.

Great focus and confidence building for kids of all ages. Very experienced staff and a great atmosphere.

We just enrolled our daughter here after an after-school program they hosted. The coaches are great and I really love the values they are teaching the kids beyond the physical stuff.

My family LOVES Cosens MMA. Coach Charlie Cosens doesnt just own a business he is creating a community. We are so happy to be part of that community. My girls, 6 & 7, have almost completed their first year in the Little Ninjas program. They have grown in their self confidence, leadership, and fitness during the course of this program. I have taken part in several Boot Camps and it has done wonders for me. Im not only getting in shape and getting stronger but building friendships and support systems. Cosens MMA truly offers something for every member of your family and you will love being part of the Cosens family. My only regret is that we didnt sign our daughters up when they younger, we would have been part of the Cosens MMA family for 6 years already and not just 1!

My name is Scott and I participated in the bjj class for a short time. With little knowledge of the sport I think the instructors were great. They are patient with students and accept you no matter what physical shape you are in. I have one issue and that I signed a contract for a year at the time that was fine. I went to class for about five months and then I had scheduling conflicts with work and financial issues. I did tell coach Burnay about it and they informed they they couldn’t let me out of the contract. I find this opposite of what they say in the beginning on helping you to get yourself to a better postion in your life but when times get tough they turn their back on you. Not the instructors but their management. So buyer beware signing a year long contract. I would recommend not.

Stopped in on my leave while visiting back home. Coach brenay and the Cosens team provided a great atmosphere on getting back into bjj. Facility in the mall town centre is top notch and all the students were having a blast!

I have gone to here for almost a year and it is great. The coaches are friendly and helpful and I would highly recommend this for anyone.

Cosens has great coaches and is an excellent learning experience that a child can carry through out their entire life.

Great atmosphere and coaches to go with a wonderful environment for the little ones to develop.Here on the buddy week invite through a friend and could not have expected more for our first time here.

Cosens MMA has been a tremendous asset in helping with my sons development. Over time he has had the ability to gain better focus and coordination. The coaches are absolutely wonderful with everyone! My husband has participated in several of the fitness boot camps, which has helped him achieve his goal weight.

Both myself and my daughter really enjoy and appreciate the knowledge and workouts twice a week. Thank you Cosens Team!

Both of my kids attend classes at Cosens. They LOVE IT!! The coaches are fantastic with them and they are learning so much!!

Great place to teach respect and the staff is always helpful no matter what you need.

Coaches are great, lessons are good priced and a very good learning experience for kids all age, my son absolutely loves it and it was the best decision we ever made putting him in cosens mma. Thank you for everything you guys do!

Everyone is extremely positive and professional while teaching children self discipline and good life skills! Highly recommend them!

Ive been attending for about 3 years now cosens mma has helped me so much the coaches are so amazing and they all are great with kids.

My son started at Cosens when we was 3. Very shy didnt want to socialize. The coachs there helped him out so much. He has been going for 3 years now and he continues to grow. He uses the life skills that they teach him every day. Cosch Greenwood is amazing with the kids he also make a point to meet and greet parents when he gets a free minute. My son was struggling at one point and Coach Greenwood took time out of this day to meet with my son for a one-on-one class to help him out. If you are looking for a martial arts class for your children I highly recommend Cosens. You will not regret it.

I have been going to Cosens MMA classes for almost a year now and my experience with the staff was amazing the classes are so much fun its a great work out. i must say you have to try out Cosens MMA classes.

Love this place. The coaches are very good. You can really see a difference in our 4 year old. Highly recommend checking this out for your children.

Awesome coaches and students. Who knew that at 54 years old I would be learning BJJ and cage fighting skills and loving it. Its like working out with family because everybody there (students and coaches) will help you to succeed.

After my daughters first birthday, I decided it was time to get back into shape! After trying several different gyms, diets and classes nothing seemed to hold my interest. Until I stumbled upon a video from Cosens MMA. Within the next couple days I was in the gym meeting with the coaches and getting a private lesson to see if this was the thing for me. Ive been training at the gym for almost six months now and feel amazing. The testing system is a great motivator and keeps you interested. Having short term and long term goals is such a great way to make and see your progress! Not only am I getting a great workout physically, but I am growing as an individual in my confidence and spirit! Would highly recommend the gym to anyone looking for a great workout, learning experience, and all around better way of life. :)

*** Be warned people get free T Shirts for leaving good reviews on here. ***Pros:•Clean and friendly environment.Cons:•Charlie Cosens is never actually at his own gym.•Other coaches aren’t necessarily the best trained in Brazilian Jiu Jitsu, have training in other martial arts.•Have to pay $50 cash to “test” if you want to progress further in belt rankings. Other gyms do belt promotions when they feel you’re ready.•Once you pass blue belt you don’t necessarily learn much more. As opposed to other gyms that black belts teach you and work with you 1 on 1.•Ridiculously expensive compared to other gyms in the area.

My daughters love Coach Greenwood and Coach Abernathy. They teach them discipline while still having lots of fun.

The coaches are amazing! The Little Ninja program teaches confidence, focus and civic responsibility. All around great activity for kids!

Our family loves this gym! The instructors are amazing, positive, and take a genuine interest in the development of the students.

Coach Greenwood is so great at helping his students achieve! He always encourages and affirms the efforts of all his students!

We have been doing tiny ninjas since November and we absolutely love it. The coaches are amazing with our little guys his behavior has improved as well

Great place, great atmosphere, wonderful Coaches. Everyone is so friendly and they are absolutely amazing with the little ones! Highly recommend this for any individual

Such an amazing place. Coaches are always so positive and amazing. Best thing that we have done for our son. His confidence has increased and hes learned so much from the coaches.

Ive been coming to Cosens for just under a year. All the staff are extremely friendly, helpful and concerned about your progress. Id recommend them to anyone.

My son has only been going there a short time, but in that time, the staff has gone out of their way to make sure he is comfortable and that I am. His coach comes up and talks to me before the classes, everyone is so friendly, we even got a hand written thank you for coming in. This place has class and they really care about their students and their families. I hope my son continues for a long time!

Best place ever! For everyone... Men, women, children, the instructors are awesome. The classes are well structured. Ive learned so much. I recommend it to anyone.

Everyone makes you feel like family. They go above and beyond to help with anything you need. From troubles at school, self confidence, and helping with children with ADHD. I would recommend anyone try it out. They offer many types of class for all ages.

I am giving all the coaches a five star rating they are amazing. They are all willing to help the kids in any way they can.

My kids started training in the little ninjas class and I thought it looked like fun so I tried it and have been training for 2 years now and still having fun. Great family atmosphere with no egos.

Very loving and amazing kids/coaches happy to attend always have so much fun!

Signed up my daughter last April...she was having issues in school being bullied. I deciced to enroll her in a self defense class. I gave Cosens a call and it has completely changed her life and ours. It has given her self confidence and esteem. Taught her how to react to bullies and giants. Life skills that are difficult to teach to children. Charlie and his team welcomed our whole family to join theyre Team. My wife and I decided to enroll in classes and make life improvements of our own.I highly recommend this place to anyone in search of self improvements and self defense and all round good time!

These coaches are awesome! Coach Greenwood , Abernathy ,Bernay Great environment and kids loves it

Us and our kid really enjoy this place and coach spy is the best

I have two children going on their second year of MMA and theyve grown in all areas of their teaching, as well as enjoying time with their awesome instructors! I personally stepped outside my comfort zone 2 weeks ago and joined the 6 week fitness boot camp...I really am not one to exercise and am using muscles I didnt even know I had, haha! But honestly, the owner is amaaazing, as well as those in my class being fun and encouraging to each other. .. I feel better already and will definitely be joining again. Do yourself a favor and find a class at Cosens, you wont be disappointed!!! :)

This place gets a three. I attended this place some time ago, so things may have changed. Be weary that those who write a good review about this place get a free T-Shirt.Pros:+ The coaches are super friendly!+ The coaches are willing to work with you a lot to help you improve.Cons:+ You dont get trained by the owner of the store like you do on your first day of the free trial (at least I never have, and I was part of the program for six months). You only get taught by the employees who last time I recall, have nothing better than a Blue Belt according to official Jiu Jitsu Rules.+ Fairly expensive.

My daughter just loves going to Little Ninja class every Tue & Thur. She has learned so many life skills. She uses them at home. Shes so well mannered. I get complements all the time. And the coaches are the best.
