BJJ Core Concepts is an iPhone app developed by Grapplearts Enterprises Inc. It is a comprehensive guide that aims to help individuals learn and master Brazilian Jiu-Jitsu (BJJ) faster by understanding the underlying concepts and principles of the martial art.

The app provides users with a step-by-step formula to hack BJJ and become an effective grappler. It emphasizes that jiu-jitsu is not about extreme strength or athleticism, but rather about using positioning, leverage, and momentum to gain an advantage over opponents. By applying these concepts, users can improve their technique retention, efficiency, and ability to defeat bigger and more experienced opponents.

The app covers essential concepts such as base, posture, structure, leverage, framing, and control of momentum. It offers concrete examples to help users apply these concepts directly to their grappling, enabling them to shortcut their way to success on the mats.

BJJ Core Concepts offers an hour and 33 minutes of video-based instruction, delivered by two BJJ black belts. The instruction is concise and practical, with menus to facilitate learning and retention. The app is suitable for practitioners of BJJ, no-gi submission grappling, MMA, and self-defense.

Rob Biernacki, a BJJ black belt with extensive training and competition experience, and Stephan Kesting, a BJJ black belt and founder of Grapplearts.com, are the instructors behind BJJ Core Concepts. Both instructors have a proven track record of teaching the underlying principles of jiu-jitsu and helping grapplers improve their skills.

Whether you are a beginner or an experienced practitioner, BJJ Core Concepts offers a valuable resource to enhance your understanding and application of BJJ concepts and principles.
