Pulahan Derobio Eskrima in Chula Vista's northeastern Rolling Hills corridor preserves a Filipino martial arts lineage descended from Great Grandmaster Braulio Tomada Pedoy, teaching stick, blade, and empty-hand combat from 821 Kuhn Drive. The Siangco Collective's Counter-Strike methodology—block-for-block, attack-for-attack, and joint manipulation across Largo, Medino, and Corto ranges—builds the adaptive reflexes that cross-train with submission grappling systems at 10th Planet Jiu Jitsu - South Bay. Hall of Fame-inducted instructors lead all-ages classes through Derobio Method footwork patterns, disarming sequences, and limb-destruction drills rooted in the combat traditions of the Visayan Islands. The academy has hosted the annual Honoring the Legends of Filipino Martial Arts tournament at Chula Vista's Otay Recreation Center since 2022, drawing Eskrima, Arnis, and Kali practitioners from across Southern California. Drills progress from single-stick sinawali patterns through double-stick redonda flows and live-blade demonstration techniques, requiring the grip strength and rotational conditioning available at San Diego Strength and Wellness. Senior-rank students execute the full striking matrix at combat speed against padded targets, integrating joint locks, takedowns, and knife-disarm sequences within continuous-flow counter-for-counter sparring.
