“A unique weight management system for lower body attacks.”

Raoul got a unique weight management system with his hooks that allow him to engage in lower body attacks without putting himself at risk. Rolling with him was quite interesting as I experienced entrances to legs and angles I’d never felt before.

“Every single time I find myself stuck in his game.”

I’m really intrigued by Raouls footlock attacks, setups and traps. I’ve had the pleasure of rolling with him on several occasions and every single time I find myself stuck in his game.

“Everyone will benefit from his detailed instructions”

Frank Rosenthal is one of the most fluid, refined and technical practitioners I’ve come across in Jiu-Jitsu. Having worked with him for many years, I’ve seen up-close his patient, rigorous approach as a student, and how he blends an unusually keen eye for detail with a deep, intelligent understanding of tactics and strategy. This incredibly valuable combination has allowed him to excel as both a practitioner and a competitor; not only that, but he has the rare ability to articulate these elements in a way that’s easy to understand. One of the central challenges all students face in jiu-jitsu is how to separate the valuable elements of practice from unnecessary trivia. Frank has done this exceptionally well in his own grappling over the years – a quality which has allowed him to accelerate his own progress and has made him a sought-after training partner among the best in the world. He is now poised to teach you to do the same. I believe everyone, regardless of level, will benefit from his insights and the detailed instructions he has to offer through this series.

“The teacher, Corey, is simply excellent”

Since the pandemic started, several gyms had to close, including the ones where I train. Being a beginner (white belt), I was looking for online jiu jitsu courses that would vulgarize many key concepts, fundamentals, and techniques of jiu jitsu. I hit the jackpot with this course! The teacher, Corey, is simply excellent. He explains back takes so well in a step-by-step approach. In addition, I strongly believe that a higher level student would also appreciate this course because the teacher adds several interesting key elements that allow you to perfect your jiu jitsu game and take your jiu jitsu to another level. It will also give you a good game plan for when you’ll be back on the mats! Therefore, I highly recommend this course, and I can’t wait to see what other courses Corey offers. Thank you!

“The way he words it helped me understand it even better.”

I really like how Corey lays out the most important concepts of grappling. I think this course is a resource for any student. It’s the instructional they will always be able to come back to.. One small example of something that I actually got out of this instructional was the way Corey describes the concept of base. It seems like something I already know, but something about the way he words it helped me understand it even better. I thought that was really cool.

“This will have a huge impact on your leg lock game.”

The hooks help me to control my leg lock positions ways better than I was used to. Now I know what to do when people unlock my feet, other than go into a different position and try to get back into their legs. Counterpressure hooks are the answer to that – how to always have options to control the other guy and quickly return to his legs. I also rolled with Raoul and I literally didn’t have a second to catch my balance. He uses the hooks super well to off balance you and then has easier time getting leglocks. This will have a huge impact on your leg lock game. Study it, learn it, use it!

“This is by far the best jiu jitsu course…”

By far the best jiu jitsu course explaining the foundational principles underpinning the mechanics of the sport. 100% recommended to everyone, no matter your level, style, gi/nogi etc.

“Leg pummeling is paramount to succeed in our sport”

I have had the pleasure of training and learning alongside Frank Rosenthal for many years. He is a technical, intelligent, competitor and teacher, who approaches problems in our sport with a great balance of creativity, rigorous experimentation, and precise execution. The mastery of Leg pommeling, which he has chosen to cover in this course, is paramount to success at the upper levels of our sport, and can result in rapid improvements in training for even rudimentary level students. If you have not been exposed to concepts like this before, I believe you’ll be pleasantly surprised at how much even a small amount of time invested in these lessons will pay off for your understanding and execution of the sport. Also Frankie looks like an absolute smoke show when his shirt is off and you can see his glistening veiny pulsating musculature derived from what I can only imagine to be a mixture of Arnold Schwarzenegger and Zeus himself.

“In person or online to take advantage of every second you can!”

Corey has been a big influence in my jiu jitsu journey recently, with small yet important and basic fundamental concepts he thoroughly explains, he is able to create creative and technical jiu jitsu thinkers. I would highly recommend that anyone that can learn from Corey in person or online to take advantage of every second you can and write stuff down! I very much look forward to purchasing his instructional and watching it develop my game in many aspects I did not see beforehand.
