Ascent Brazilian Jiu Jitsu
A Coralville BJJ school that works in different ways for everyone who shows up. Beginners get to gently wade into real techniques rather than being thrown to the sharks at the deep end. Intermediate students get to keep moving forward instead of just sitting through the basics on a loop every class. This school is safety-focused, and trains the mind and the body at the same time.

What they do
Ascent runs Brazilian jiu jitsu classes on 5th Street in Coralville, a few minutes from downtown Iowa City.
Owner Mike Warner is a black belt — and a really nice, humble, technically proficient instructor. Mike and his main coach Josh Guhl are both amazing and teach kids (ages 4–15) and adult classes. As of October 1, 2026, they are the only BJJ school in Iowa that is fully accredited through Academy Safe. That means the owner and coaches have passed a professional background check and completed U.S. Center for SafeSport abuse-prevention training, concussion training, and CPR / First Aid & AED certification. Belt ranks and lineage are independently verified. The gym keeps cameras on the training areas, active liability insurance, a valid business license, and an on-site AED.
Ascent meets people at whatever level they might be when they walk through the door and helps them progress far beyond that. Questions are always encouraged in a positive and supportive environment. They don't just teach the sport side of BJJ. They also teach the self-defense. Families from Coralville, Iowa City, Tiffin, and North Liberty train here, but make sure that it's close enough to where you live. A gym you will not drive to is a gym you will not attend. They offer a free week if you want to try out the mats before you commit.

On a personal note
I have trained in these types of techniques for over a decade and have seen first-hand the value of BJJ classes. It has a unique way of giving students the ability to find clarity in chaos, relieve their stress, challenge themselves mentally and physically, and hang out with their peers in a healthy way — all while creating a safer and stronger community.
Prior to signing my kid up with Ascent, I did my due diligence and visited the other schools in Iowa City. The instructors at those schools were also skilled, but one thing or another kept falling short. Maybe the class size was too big and there weren’t enough coaches, so numerous mistakes went by uncorrected during drills. Maybe the focus was all wrong — safety wasn’t a priority, too much ego was involved, and so on. All I know is that Ascent was in the Goldilocks zone and checked all the boxes for me personally. My kid is currently training here and progressing while having a blast.
What even is Brazilian Jiu Jitsu (BJJ)?!
It started in Japan as a way to control someone in a full suit of samurai armor, where a strike would not do much. Mitsuyo Maeda carried that art to Brazil, and the Gracie family reworked it so a smaller, lighter, or weaker person could beat a bigger opponent with leverage, position, and timing instead of strength. When you are rolling in class, you are locked into a physical chess match with another person. There are no strikes. You take them down, advance your position, and look for a way to control or submit them. The workout is HIIT (High-Intensity Interval Training), hard bursts and short rests, and it builds grip, hip mobility, core, and the range of motion most adults lose from sitting all day. Most dangerous situations in real life end up very close to the other person, or on the ground, which is exactly where this training is focused. The goal is to control them rather than damage them. The ability to do damage is there, but it is not always required to end the fight.
It is also hard to think about the stress in your life while someone is trying to submit you, so the anxiety and tension a lot of us carry gets burned off in class. People who stay with it report less anxiety, better sleep, and a clearer head. A study of veterans who trained for 40 sessions found lower PTSD symptoms, less depression, less anxiety, and less drinking. Every round is a problem you solve under pressure, with instant feedback on whether the answer is working. People who train together start describing the school as a family, and the confidence comes from knowing you can handle yourself and that you are getting better at something hard. BJJ also keeps you humble. Everyone gets caught in a lock or a choke on a regular basis.
It trains the heart, the muscles, the joints, the head, and the social connection in the same hour. The benefits stack the longer you stay, which is why people who have been at it for years call it the best single thing they do for their health.
