Had to request a refund because the app doesn’t work. After you pass the first terms page none of the videos work. All that you can see when you click on video link is a white screen. I really wanted to check this out, super bummer.

After buying the app, I am unable to view any videos. I will be requesting a refund because I am not getting what I paid for. 2 Stars

I’ve had a similar BJJ experience that Rob refers to as a being a “move chaser” and thinking that the way to win revolves around a library of moves that “surprise” your opponents. His conceptual approach is so much better than your typical class or app experience.

I always heard coaches tell me to break down my partners and make them screw up and this explains Black belt knowledge to even non white belts.!

I enjoyed the app. The program ran seamlessly. The curriculum definitely gave me a better understanding of the game. Kesting does a great job of raising questions, which brings out the vital details.

I'm nearing Blue belt. Besides helping me understand some fundamental principles of BJJ, I have gone back to review certain sections and surprise surprise I learned additional/ different points. I saw why some of my frames weren't really frames or why I was getting flattened out and how to avoid it (posts and force vectors). So I think these apps will continue to be valuable even as I progress in rank / skill / experience. Oh, be advised that Rob's humor is not politically correct, but I wasn't really bothered by it. Enjoyed it!

I really enjoy how Rob breaks down BJJ with his core concepts. Learning these fundamental principles instead of just moves or techniques will really help improve your game!! Another great app from Stephan and Grapplearts!!

This app will change how you understand your bjj game and allow you to learn new techniques within an overall context of your game as well as analyze why techniques you already "know" are not working. Rather than going back to the "drill it a 1000 more times" drawing board (which simply ingrains the bad habit) you can use the app to find the guide posts you need to improve your technique and integrate it into your game. Well worth your time and money.

Some people are natural athletes with an innate sense of how to use their body, and then there's the rest of us. This app, while helpful for everyone, is downright essential if you find yourself analyzing every aspect of your drills or struggling with how to react in unfamiliar positions or against new drill partners. Rob's breakdowns are clear, cohesive and comprehensive. You come away ready to implement his tips the same day.

I own a ton of BJJ instructional content, including most of the Grapplearts products. Always well produced, with excellent video, and audio. This material with Professor Biernacki is particularly good. It focuses on concepts, as opposed to giving you another bunch of techniques. As an older, smaller student, I've found it to be very helpful, as well as inspiring.
