We tried a couple of the schools, but Warrior was the most accomodating and really tried to help him over what had happened previously and to make him feel a part of the Warrior family. I've found that they have the best balance between "stand up" training and "on the ground" work, done in a safe, controlled environment, with great instructors who really work with the kids to create a positive environment. The training includes an emphasis on respect, not only for the instructors at the academy, but for parents, school teachers and their peers, helping them to become "bully proof" without becoming bullies themselves. Additionally, parents can train for free, in classes set up for them. My wife participates in the stand up and grappling classes. You'd be hard pressed to find a place with a better set of instructors (the new McKinney instructor is a BJJ master from Brazil).

He is very technical and informative. He knows how important it is to build a good foundation to prevent injuries and roll safely. Children do well in his program because it is structured. He has taught my daughter focus & discipline! The school itself is incredibly clean. Restrooms are extremely clean! Very nice mats! Nicely ventilated space! I highly recommend this school for both children and adults interested in jiu jitsu. I can't say enough great things about Professor Inacio and his school. We cannot wait to return.

Dan A. McKinney, TX…read more Jan 6, 2024 I began training with Professor Inacio and his most excellent coaches when I had accumulated 68.5 years of mileage in life. That ain't as big a number as it may sound like. I was surprised that my wife for those decades was supportive of my beginning at such a school. I assumed then that her enthusiasm had something to do with a large life insurance policy on me that was in effect at that time, 2.5 years ago. The policy is lapsed, and she is still supportive, so maybe not. I am not a fast learner in this domain, but I am a learner. Sometimes I can even coach a move or two with my workout partners. Usually, I'm the hapless nail, rarely the hammer. This is not a bad thing. It is necessary. The people who show up and continue to show up to train seem to me to define a psychographic group that is a group that you benefit by being close to. Do hard things and keep doing them. Then do them some more. Then do them some more. Special people congregate here. Right here. Things change while practicing this discipline. For me, positively but slowly. For normal people, positively but much more quickly. This is the place to train and to get as effective as situations may require you to be later.

But if you are looking for a place to sharpen your character while you sharpen your skills, Sharpen Iron Academy (SIA) in Plano is in a league of its own. ​At SIA, you aren't just a number; the professors know you by name and are genuinely vested in your success both on and off the mat. This is a culture of discipline, accountability, and mentorship where the "iron sharpens iron" philosophy is lived daily. ​Whether it's the kids' classes, the youth program, or the specialized women-only classes, there is a deep level of trust and a guaranteed safe space for every student. It is more than a gym--it is a community and a family where you are pushed to grow in a supportive, high-level environment.

My…read morebackground of Brazilian Jiu Jitsu was virtually non existent, but several coworkers sang its praises and how it worked wonders for their children by teaching discipline, focus, work ethic and confidence. Their Godfather helped me research studios and after reading the CV for their head instructor Professor Henrique it was time to give it a shot. They had a lot of fun during the trial class, but they were nervous to start, not wanting to be away from Mom even though I was only three feet off the mat. Thankfully SIA instructors are not only skilled at keeping students engaged during training, but are very family centered, patient and caring. They were able to connect with each one of my kiddos so that they felt comfortable training as I looked on. By parent teacher conferences in February their preschool teacher let me know that both had grown so much in maturity and confidence and was curious to know what I was doing differently. Almost two years later the twins are well adjusted, focused and always happy when they step off the mat after an hour training session. Professor Henrique, Professor Lucas, Professor Matheus, Coach Queila, Coach Enrique, Coach Ian, Coach Ella, and Coach Anthony have become family and there is no other place I would have my children be twice a week. They offer adult classes in the morning and evening and several of the parents after seeing the transformation in their own children have started to earn their stripes as well.

EXTREMELY UNETHICAL BUSINESS PRACTICES!…read more I joined the gym in early 2024 and cancelled my membership in June of 2024. Apparently due to some sort of miscommunication, something went awry with my cancellation and it was either not received, not processed, or both. A YEAR AND A HALF AFTER THE FACT - in October 2025, I receive communication from a debt collector saying that I owe almost $1300 in back charges. This gym NEVER, NOT ONCE sent me any communication informing me that there was an issue with my account. I was not provided any notice whatsoever that there was a problem - no bill, no phone call, no text, no mail. Instead they just kept accruing charges FOR A YEAR AND A HALF without my knowledge and hit me with a $1300 collections bill. I was never given an opportunity to correct this beforehand, before it got out of hand. This is NOT the way a reputable business conducts themselves.

Lots of taping over cushion cracks instead of replacing etc. And fitness equipment is definitely aging. My biggest frustration and cause for me to cancel my membership was over the most ridiculous business practice. I set up my payments with auto pay from a credit card. About a year into my membership the credit card expired and I forgot to update my card. ONE DAY after the due date I get a harassing collection call. A simple text message or email asking me to update my card would do just fine. Then I see a $25 "processing fee" on my credit card after I updated it. AC (the owner) replied that he's not charging me, but it's the billing company he outsources to and they charge when an account goes to collections. Sorry bud, but you picked them and they represent your name and reputation. Needing to update a credit card within a few days of due date isn't something that should "go to collections" in the first place. The fact they're willing to let a member leave over something so trivial and typical is beyond me. Recurring revenue on monthly auto pay is the life-blood of many businesses. There are plenty of payment solutions in the market that would make life easier on your customers.
