Two coaches. One ADCC-ranked competitor, one full-time youth specialist whose students have already trained at ADCC and MMA Youth Worlds. Both brown belts under Sean Stoopman, focused entirely on building your child.
Most kids gyms with elite-level coaches split their attention across adult and youth programs. Not here. Two coaches, both world-class, both committed to kids only.

Cam's full résumé
Five years coaching full-time, three of them with kids. His students have already competed at ADCC and MMA Youth Worlds — building real young athletes from the ground up.
Lyndon's full résuméSee real moments from our classes — drilling, sparring, the work that builds confidence and skill on the mat.
Most gyms with elite-level coaches split their attention across adult and youth programs. At HYR, that doesn't happen. Coach Cam is currently ranked 3rd on the ADCC 2025 circuit. Coach Lyndon has spent five years coaching full-time, three of those building youth athletes who've competed at ADCC and MMA Youth Worlds. Both are brown belts under Sean Stoopman. Both work with the same kids on the same mats.
Coach Cam is currently competing at the top of the ADCC 2025 circuit — and coaching your kid.
Coach Lyndon's students have already competed at ADCC and MMA Youth Worlds. He builds athletes from the ground up.
HYR runs no-gi only — your child shows up in athletic shorts and a t-shirt or rash guard. Patient coaches who remember what day one felt like.
Kids Brazilian Jiu-Jitsu — that's it. Focused instruction, undivided attention. No adult divisions diluting the work.
I've known Lyndon for years now. My son has attended camps run by Lyndon and Cam. He loves their style of grappling and teaching. They are both great instructors! Highly recommend!
My 13-year-old son has been training with Coach Lyndon for both jiu jitsu and strength training, and the progress has been incredible. His jiu jitsu skills have improved tremendously, and he's also gotten much stronger physically.
I can't recommend these guys enough. My kids have attended other academies but it seems like this is the place that they finally started to fall in love with jiu jitsu. Coach Cam and Coach Lyndon are exceptional with the kids.
Coach Lyndon is great! He really knows how to work with kids, making it fun while helping them learn and improve. He's professional and genuinely cares about their progress. I definitely recommend signing up — you won't regret it!
We've known Coach Lyndon for a while, and he has always been amazing with kids. He's patient, motivating, and truly cares about helping them grow both on and off the mats. Niyar has learned so much from him over the years.
Lyndon and Cam are outstanding coaches. Lyndon was my very first BJJ coach (which required no small amount of patience), and now he and Cam are working together to build something really special. They not only know the art inside and out, but they connect with their students.
Top notch instructors. Lyndon and Cam create a welcoming environment for all skill levels, and the training is both challenging and fun. Whether you're brand new to jiu jitsu or looking to sharpen your technique, this is the place to be. Great people, great training, and an awesome community.
I highly recommend Coach Lyndon and HYR Grappling to anyone. The classes and breakdown of the techniques he teaches are engaging and easy to follow. He's a great coach for all ages and skill levels.
I have nothing but wonderful things to say about this academy. The coaches are thoughtful through their training and push the kids with encouragement and enthusiasm. We are very happy with our choice to be at this academy.
If you're a parent in Northern Virginia looking for an activity that will help your child grow stronger, more disciplined, and more confident, HYR Grappling is the place to go. Their kids' Jiu-Jitsu program is a game changer!
Highly recommended. Lyndon has an exceptional knowledge of Jiu-Jitsu and a great way of breaking things down so they're easy to understand.
My kids trained under Lyndon and I can say with confidence — if you are looking for a high-level instructor, you all need to check out HYR Grappling.
Great coaches with top-tier instruction! Fun and safe environment for youths. My daughter loves training here!
Lucas and Bella loved your kids program! Highly recommend Lyndon's coaching at HYR!
Lyndon is a phenomenal instructor and always takes the time to make sure techniques are understood and questions are answered. Highly recommended!
Awesome gym and instructors!
Really good coaches. Recommend.
No experience needed. No pressure. No-gi only — just athletic shorts and a t-shirt or rash guard. Pick a class time, show up 10 minutes early, and meet Coach Cam or Coach Lyndon before the warm-up.
