Kids BJJ
Little Lions — Kids (Ages 4–6)

We build the foundational skills in Little Lions. Students work on coordination while learning plenty of life skills — respect, discipline, and confidence in a structured environment.

The Lion Cubs program kicks up the focus on technique. Classes gain intensity as we begin to focus more on grappling and sparring.
Youth BJJ · Gi & No-Gi

Ages 10–13
The bridge between kids and adult Jiu-Jitsu. Students are allowed a healthy transition that lets them take their game to the next level.

Adult Jiu-Jitsu (Ages 16+)
All levels · 16+
A competitive environment where everyone makes each other better. Foundations through All Levels and Competition classes, Gi and No-Gi.
How we train
The Constraints-Led Approach
We don't drill techniques the old way. Instead of repeating a fixed sequence in a vacuum, students are placed in constrained games and live situations where they have to problem-solve. This ecological approach is how people actually learn movement — and it produces skill that shows up when you roll.
01
Learn by solving
Game-based, adaptive training where you discover what works for your body against real resistance — from day one.
02
Built for everyone
Kids and families build foundational skills while competitors sharpen a high-level game, all in the same room.
03
Skill that transfers
Instincts built through live practice adapt under pressure — on the mat and off it.
About
Why train at Jiu-Jitsu Unlimited
Welcome to Jiu-Jitsu Unlimited, an upbeat martial arts school in Sioux City, IA. Parents, kids, and competitors get started in a supportive, professional environment where students grow and learn while having fun. Our training uses a Constraints-Led Approach (CLA) — learning through dynamic movements and live situations that optimize your development rather than rote drilling. Through this ecological approach you'll build real problem-solving skills, confidence, and a game that holds up under pressure. Families and competitors train alongside each other, and many of the highest-level competitors in the Sioux City area train with us to bring home medals. Whether you're brand new or a seasoned grappler, there's nowhere better to build your skills.
A coach who invests in how you learn
At Jiu-Jitsu Unlimited, our coaches are serious about being the best they can be — so they've
joined a community of forward-thinking coaches, led by Greg Souders, who train with the
constraints-led approach: a modern, games-based method grounded in
motor-learning science. You learn by solving real problems on the mat — and build skill faster.
