IBJJF white belts cannot use heel hooks in gi or no-gi; Illegal Moves table allows them only for adult brown and black no-gi.
Heel-hook legality changes by ruleset, belt level, age division, and gi versus no-gi.
The IBJJF Technical Fouls & Illegal Moves table — published with the Rule Book on the IBJJF Books and Videos page — marks heel hooks, knee-twisting locks, and knee reaping in every column except adult brown and black no-gi. White belts should assume heel hooks are illegal in IBJJF-style divisions.
IBJJF’s official rules-update page states that heel hooks and knee reaping for adult brown and black no-gi took effect on 1 January 2021. They remain illegal in the gi at every belt, including black belt.
Official ADCC Championship rules list any leg lock or ankle lock as legal. Some local no-gi events copy that catalog; others do not. Check the exact rulebook before competing.
- Heel hooks attack rotational knee structures, not just the foot
- Damage can happen before a partner feels obvious pain
- Fast finishing pressure is unsafe in beginner rooms
- Training partners need clear tapping habits and agreed rules
Learn positions first
Understand control positions, knee line, and safe escape timing before chasing finishes.
Separate training from competition
