Explore 580+ Brazilian Jiu-Jitsu techniques in 3D. See how a move works, study it step by step and discover what to try next. WATCH BJJ TECHNIQUES FROM ANY ANGLE Rotate the 3D view, scrub through the movement and switch between top and bottom. Follow the blue fighter to understand the position and movement before your next training session. STEP BY STEP, SETUP TO FINISH Each technique includes a written guide covering the setup, movement and finish, with key details and common mistakes. Most also include selected instructional videos to help you study the technique. WHAT COMES NEXT, AND IF THEY BLOCK IT Explore linked follow-ups and alternatives when your opponent blocks a move. Where available, the “What's next” and “If they block” sections take you straight to another technique to study. FIND YOUR NEXT TECHNIQUE Browse by goal: submissions, back takes, control, guard passes, defence, escapes, sweeps and takedowns. Search by technique names and common aliases in English, Spanish or Portuguese. Save techniques in collections to revisit before training. Want something different? Open the crate to discover a technique you have not tried or revisit one getting rusty. For gi and no-gi grappling, from chokes and armbars to leg locks, guard passes and escapes. LOG ROLLS AND FLAG PROBLEMS Keep track of what you drilled, rolled and competed. Add notes, record how a session went and flag problems to revisit. Your technique history keeps your practice connected to what you are learning. SEE THE SHAPE OF YOUR GAME Compare the techniques you drill with the ones you use in rolls across eight goals. Spot areas you practise less and find something to study next. TAKE YOUR LIBRARY TO THE GYM The technique library and training logs work offline; your logs sync when you reconnect. Instructional videos require internet and may open in YouTube. Available in English, Spanish and Portuguese. KUROBI PRO Kurobi requires a Kurobi Pro subscription. Eligible new subscribers can start a 14-day free trial. After the trial it continues at the selected plan's price unless cancelled. Prices, trial eligibility and promotional terms are shown before you confirm. Manage or cancel in your Apple Account settings. To avoid renewal after a free trial, cancel at least 24 hours before it ends. Kurobi's library is a curated reference, not a complete one: names, details and variations differ between instructors, academies and rulesets, and the 3D fighters are schematic. It supports your learning and does not replace qualified in-person instruction, supervision or your own judgment. Discover. Learn. Drill.
