5-MeO-JJ training

About

5-MeO-JJ offers Brazilian Jiu-Jitsu, Judo, and bare-knuckle striking. Our training is constraints-led and concept-driven, built on fundamentals that hold up under pressure.

We focus on principles over techniques, prioritizing depth of understanding over breadth — base, posture, connection — so students learn to adapt rather than memorize.

Everything is tested. If it doesn’t work against resistance, it doesn’t belong.
