Heel Hook
Rotational leg lock that attacks the knee through heel control — a primary finish in modern no-gi entanglements.
joint lock
Overview
The heel hook finishes by controlling the heel and rotating the foot to load the knee ligaments. Inside and outside variations change the direction of torque, but both reward knee-line control, hip connection, and calm pressure more than explosive twisting.
#Setup
- Establish a stable entanglement (ashi, single-leg X, or fifty-fifty) with the knee line pinned.
- Cup the heel so the calcaneus cannot slip; keep the toes pointed away from your finishing arc.
- Clamp your knees and hide your own exposed leg before hunting the finish.
#Execution
- Fall to the finishing hip while keeping chest and hips connected to the trapped leg.
- Rotate through the heel with your whole body, not just the arms.
- Maintain secondary-leg control so the opponent cannot turn out or stack you.
#Finishing
- Increase rotation gradually until the tap; never snap through resistance.
- If the heel slips, re-secure foot control before reloading torque.
- Release immediately on tap — knee injuries often appear after the pain signal.
⚠️
Safety Warning
Heel hooks can damage the ACL/MCL with little warning. Train only with clear rules, slow pressure, and partners who understand early taps. Do not apply explosive twists in live rounds.
Primary Targets
- Knee
- ACL
- MCL
Key Concepts
- Control the knee line before attacking the heel.
- Inside vs outside heel hook is a direction choice, not a different entanglement family.
- Body rotation finishes; arm strength alone stalls and invites counters.
Primary Entries
- Ashi garami and single-leg X when the far hip is controlled.
- Fifty-fifty when you win the primary foot and hip race.
- Scramble recoveries where a standing opponent’s heel is exposed.
Defenses & Counters
- Expect early heel hides and inside-knee pummels — re-pin the knee line before restarting.
- Watch for stand-ups that clear your secondary hook; follow the hip or disengage safely.
- If they turn belly-down, decide quickly between following for the finish and abandoning for top position.
Follow-Ups
- Straight ankle lock when heel control is lost but the foot remains trapped.
- Knee bar if the leg straightens and the hip line opens.
- Back take when they turn away to escape the rotational threat.
Training Drills
- Entanglement control rounds with no finishing allowed.
- Slow heel-hook entries to a light tap, then reset.
- Knee-line recovery drills against intentional heel hides.

Summary
Treat the heel hook as a control problem first. Pin the knee line, secure the heel, rotate with your hips, and finish patiently — that is what makes the attack high-percentage and safer to train.
