What I Do
I’m a Brazilian jiujitsu black belt, no gi coach, and physical culture expert. This website will make you a better martial artist.
Open Note Grappling helps you learn and stay organized so you can improve your Brazilian jiu-jitsu, health, MMA, fitness, and performance. This website is where I record what I’m learning and teaching.
I make content and products to help people learn and teach jiu-jitsu better.
Are you a jiu-jitsu student that wants to get better, faster?
Are you a coach that wants to be more organized and save time?
Why I Do It
The way we teach, train, and learn is largely inefficient and ineffective.
I’m testing this theory through grappling, fitness, and health in general. I’m starting to believe that this idea is the norm.
That’s why I created this website.
After all of my training and teaching I’ve come to these conclusions:
- Less is more
- (almost) Everything is good for you to a point - the opposite is true as well
- Combat sports, fitness, and health in general are plagued with bad science and low tech solutions making for massive inefficiencies and creating ineffective end users
I’m publishing what I’m learning, teaching, and having success with so you can learn, train, and teach better.
Testimonials
“I LOVE the jiu jitsu notebook. It's so well made. It's super intuitive and well designed.” ⭐️ ⭐️ ⭐️ ⭐️ ⭐️Joe Mayall, Blue Belt
I was having a difficult time remembering what I went over with my students. Posting lessons with video links when possible allows my students to review or catch up if they miss a class. They love that we are more organized. I would recommend The Jiu-Jitsu Coach OS for both students and instructors - the customizability of the Jiu-jitsu Coach OS is a massive plus.⭐️ ⭐️ ⭐️ ⭐️ ⭐️
