The Matrix Jiujitsu — Master the flow. Own the matrix. Stop guessing what to drill next. The Matrix is the BJJ companion that turns the whole game into one map: techniques, follow-ups, counters, and transitions—so you can build a real gameplan and track it session by session. WHAT YOU CAN DO Explore the matrix — Browse techniques by category (Guard, Takedown, Guard Pass, Sweep, Submission, Defense). See follow-ups, counters, and escapes so every path from A to B is clear. Build your gameplan — Chain techniques into combos that match your style. Save multiple gameplans (e.g. “My A-Game”, “Competition”), attach them to training sessions, and see which paths you’re actually hitting. Track every session — Log date, duration, techniques used, and gameplans. Add notes and mark what worked (hit, drilled, failed). Watch your success rate and top techniques over time. Get competition-ready — Add competitions, track weight and weight cuts, and keep your category and timeline in one place. Save what matters — Favorite techniques for quick access and build a personal library that grows with you. Filter by belt — Focus on what’s right for your level (White through Black) so the matrix stays useful, not overwhelming. WHY IT STICKS Your progress is in one place: gameplans you built, sessions you logged, and the matrix you’re actually using. Come back to plan the next training, review last week’s notes, or add one more technique to your chain. The more you log, the clearer your game becomes.
