Sign up online to skip the $10 late fee and help us focus on coaching.
We want our coaches teaching and mentoring, not stuck behind a desk doing paperwork. Please sign up online before you head to the gym for your boxing or wrestling session. This ensures we have an instructor ready for you and allows us to spend the entire class working on your fitness and skills without any distractions.

From the Ring to the Community
A Message from Coach Jerome Jansen
I started out in combat sports back in middle school, eventually competing in the Golden Gloves and coaching varsity wrestling for nearly a decade. I opened JJ’s Boxing & Wrestling to create a place where people could build genuine confidence and strength. While I love seeing our athletes hit their goals in the gym, I am even more proud of who they become outside of it. I want every person who walks through our doors to leave with a sense of self-worth that lasts long after the workout is over.

Fighting for Fitness
A Different Kind of Gym
We have created a high-intensity environment that is actually welcoming rather than intimidating. Our 'Fighting for Fitness' approach means you get all the benefits of professional boxing and wrestling training—like better stamina and muscle tone—without the risk of getting hit. In our circuit classes, you are the one doing all the hitting. It is an incredible outlet for stress and a great way to master technical skills while focusing on your own well-being.

Real Experience in Your Corner
Expertise and Mentorship
Our coaching staff brings some serious experience to the Sun Prairie community. Coach Adam Zimmerman has a background in regional championships and state-level coaching success, while Coach Edwin Bonayon was the #2 ranked wrestler on the All-Marine Wrestling team and a professional MMA fighter. We keep our operations simple so our instructors can spend their time teaching instead of doing paperwork, making sure you always get the hands-on guidance you need.
