Kids Summer Jiu-Jitsu

$125 - Register

June 23 - August 25, 2026
Eau Claire, WI - Headquarters Location

Looking for the perfect summer outlet for your child’s energy? The Club 37 Jiu-Jitsu Kids Summer Program offers a fun, safe, and highly structured environment where kids (ages 6+) can learn the foundations of Brazilian Jiu-Jitsu. Known as the "gentle art," Jiu-Jitsu uses leverage and technique rather than brute strength, making it an incredibly empowering martial art for children of all shapes and sizes.

Through interactive drills, movement-based games, and hands-on practice, our program goes far beyond just physical fitness.

Why Kids Thrive in Jiu-Jitsu:

  • Rock-Solid Confidence: As kids master new techniques and solve "physical puzzles" on the mat, their self-esteem skyrockets—a confidence that carries over into school and social lives.
  • Discipline & Focus: BJJ teaches children the value of listening closely, following multi-step directions, and setting personal goals.
  • Coordination & Body Awareness: Fun, dynamic movements improve your child's balance, agility, and functional core strength.
  • Respect & Camaraderie: Our community-focused space emphasizes sportsmanship, safe practice, and mutual respect for coaches and training partners alike.

Give your child the tools to stay healthy, build life-long resilience, and make great new friends on the mats this summer! Space is limited—secure your child's spot today.

Bigger Than Any Single Team

At Club 37, we believe Jiu-Jitsu is about community over politics. Growth happens when we share knowledge, experience new styles, and build a tighter local scene. Whether you want to get extra competition rounds, flow roll, or swap technical details—you have a home here on Sundays.

Welcoming the Chippewa Valley Grappling Scene

We want to give a direct shout-out to the incredible martial arts academies making waves in our region. If you train at, coach, or represent any of these local schools, our mats are explicitly open to you:

Ronin Fitness (Banbury Place)

Much respect to the competitors and dedicated practitioners coming out of the Madison Street crew.

Campeão Jiu-Jitsu Eau Claire (Mall Dr)

Shout out to Coach Justin and the grapplers bringing that technical Master Leão Teixeira lineage.

The Center for Combat Arts

Welcoming all American Jiu-Jitsu and practical self-defense practitioners looking to log live mat hours.

Zimmerman’s Freestyle Martial Arts

To any multi-discipline martial artists or cross-trainers looking to sharpen their ground game.

Traveling through West-Central Wisconsin or training at an unlisted club? You are just as welcome. No politics, no mat fees—just good training.

What To Expect

No mandatory line-ups or uniform restrictions. Grab mat space to warm up, solo drill, or catch up with training partners.
