Grapple Flow is the position map every grappler wishes they had on day one. Every position. Every transition. Every submission. All connected on one interactive graph — across BJJ, Catch Wrestling, Judo, Wrestling, and Sambo. — BUILT FOR HOW GRAPPLERS ACTUALLY THINK — Grappling isn't a list of moves. It's a network. Side control connects to mount connects to north-south connects to back. From every position, there are attacks, escapes, and transitions. Grapple Flow shows you the whole map — and lets you walk it. Tap any position to see: - Every attack you can hit from there - Every escape you can chain - Every transition that links it to the next position - Video for the techniques (255+ wired and growing) - Common counters and your opponent's likely reactions — FIVE STYLES, ONE LANGUAGE — Toggle between Brazilian Jiu-Jitsu, Catch Wrestling, Judo, Wrestling, and Sambo. See how the same position is attacked differently in each style. Cross-train without losing the thread. — PATHS: PRE-BUILT CHAINS + BUILD YOUR OWN — Common Chains: 78 hand-crafted multi-branch sequences across the 8 most-attacked positions (Closed Guard, Half Guard, Mount, Side Control, Back Control, Standing, Spider Guard, X-Guard). Each chain shows the initial attack, the opponent's likely reaction, and your follow-up — with hand, hip, and foot logic spelled out. Custom Paths: build your own sequences from any starting position. Save them, name them, drill them. — TRAINING JOURNAL — Log every roll: partners, submissions landed, submissions given up, what worked, what didn't. Tag partners by username. See your win/loss by opponent. The stats surface patterns you can't see in the moment. — MY GAME + BELT TRACKING — Map your A-game. Mark the positions you live in and the ones you avoid. Track belt promotions and stripes. Set goals. Watch them close. — FREE + PREMIUM — Free: explore the position graph, watch technique videos, browse the glossary.
