On June 23, 2025, Arman Fathi—Gracie University and 10th Planet’s only dual black belt—led a high-level seminar focused entirely on the Twister, one of the most iconic submissions in the 10th Planet Jiu-Jitsu system. The seminar broke down the Twister’s core mechanics, entries from various setups like lockdown and truck, and detailed transitions from the back. Fathi’s teaching style balanced technical depth with practical application, offering insights that bridged fundamentals and competition-level execution.
