If you love GRJJ, one of the easiest, and BEST ways you can support us costs absolutely nothing.

LIKE & SHARE OUR SOCIAL MEDIA POSTS.

Share a post to your story. Send one to a friend. Share our page on Facebook or Instagram.

Why does it matter?

Because someone on your friends list has probably been thinking about trying Jiu Jitsu, either for themselves or their kids, and simply seeing a friend they trust training at Ground Rules might be what gets them to finally walk through the door.

It takes you a few seconds. For us, it can make a HUGE impact.

⭐️ Another huge way to help: leave us a 5-star Google review.

If you love training at GRJJ, tell people why. Taking a couple minutes to share your experience helps new people find us and means more than you probably realize to a small, family-owned gym like ours.

LIKE. SHARE. REVIEW.

That’s it. No cost. Just a few minutes of your time — and an enormous help to Ground Rules.

Thank you for continuing to support GRJJ and helping us grow. 💙

Joining ANY mixed martial arts school can be intimidating, we get that. At Ground Rules, we make sure everyone feels safe and comfortable with the gym. The hardest part is stepping on the mats for the very first time, once you do, you’ll never look back.

Come check out Ground Rules in Downtown Tinley Park to experience and welcoming, family friendly, hard working atmosphere. You won’t be disappointed. Your first week is on us and we have several promos that we offer. DM us for more info or just walk into the gym.

The calm before the storm. 🥋

A few minutes before class……

Clean mats. Empty room. Not a sound.

Then we open the doors.

Kids running in. Parents grabbing seats. Coaches getting to work. Teammates drilling, rolling, learning and having fun.

This is what Ground Rules is all about. We’ve built this for our community.

Want to see what all the chaos is about?

Come try a FREE WEEK with us.

You don’t have to “get in shape first.”

You don’t need experience.

That’s what training is for. Let's go!

Everyone on these mats started as a beginner at some point.

Come train with us at Ground Rules Jiu Jitsu and see what it’s all about.

It's always fun at Ground Rules. 🥋

Yea, we teach kids Jiu Jitsu but what happens on these mats goes well beyond learning techniques. These kids are built different.

They learn how to be confident.
How to work through something that's difficult.
How to win with humility and lose without quitting.
How to listen, learn, support their teammates and keep showing up.

They make some pretty great friends too!

These are the moments that make us proud of what we're building at Ground Rules.

If you've ever wondered whether Jiu Jitsu might be a good fit for your child, come give it a try.

Your first week is free. No contracts. No pressure. Just come train.
