Specialization
Leg Lock System
Heel Hook
Inside and outside heel hooks from saddle, 50/50 and outside ashi garami. The highest-percentage finish in modern no-gi grappling.
Toe Hold
IBJJF-legal at brown belt and above. Devastating as a secondary attack when combined with knee bar threats from ashi garami.
Knee Bar
Entries from top, bottom, and transitions. One of the most underrated submissions in modern grappling.
Saddle / Honeyhole
The control position that unlocks the entire leg lock game. Master this position first — everything else flows from here.
50/50 Guard
Offensive 50/50 with heel hook and ankle lock attacks. Not a stalling position — a finishing position.
Outside Ashi
The entry point to the entire leg lock system. Single leg X to outside ashi garami — from guard pull to heel hook finish.

★★★★★
"Daniel spotted three things in my rolling I'd been doing wrong for months. The detail in the breakdowns is unlike anything else out there."
