The Leglock Defence family covers all defensive techniques against leg-based submissions including heel hooks, kneebars, toe holds, and ankle locks. [1] Leglock defence has become one of the most critical areas of submission defence in modern grappling due to the explosive growth of leg lock offence in competitive BJJ and MMA. [1],[2] The primary defensive strategies are the boot (hiding the foot to prevent grip), hip pressure (driving the hips toward the opponent to relieve rotational force), and leg pummelling (freeing the legs from entanglement). [2],[3]
История и происхождение
Leglock defences were historically underdeveloped in BJJ compared to upper body submission defence, as the IBJJF's restriction of heel hooks slowed the development of comprehensive leg lock defensive systems. [1] The revolution in leg lock offence led by Dean Lister, John Danaher, and the Danaher Death Squad during the 2010s forced a corresponding revolution in leg lock defence that has become essential at all levels of competitive grappling.

Биомеханический механизм
Primary Action — Using foot positioning to control range and angles — maintaining optimal distance relative to the opponent
Joints Involved — Ankles (pivot and directional changes), knees (level maintenance), hips (balance and weight distribution)
Force Vector — Multi-directional — lateral steps, pivots, and retreats adjust distance and angle simultaneously
Distance Principle — Managing the distance between fighters is the most fundamental defensive skill — controlling range dictates which techniques are available
Позиция и вход
From clinch or ground — When the opponent secures a controlling grip, use two-on-one, stripping, or peeling motions to break their hold
As preemptive defence — Break the opponent's grip before they can execute their intended technique

✓Leglock defence is essential in modern grappling — the leg lock game has evolved dramatically and every grappler must have reliable defensive systems (Danaher, Leg Lock System, 2018)
✓The hierarchy: (1) don't enter the entanglement, (2) fight for inside position, (3) hide the heel, (4) straighten the leg, (5) clear the entanglement
✓Inside position (your knees inside the opponent's legs) is the single most important concept — whoever has inside position controls the leglock exchange
✓The boot (hiding the heel by pointing the toes and flexing the foot) is the fundamental immediate defence against heel hooks
✓Against kneebars, straighten the leg to remove the fulcrum angle — a straight leg cannot be kneebar'd
✓Leg pummelling (swimming your legs inside) is how you win the inside-position battle and prevent the opponent from attacking
✓In MMA, leglock defence must account for ground strikes — don't stay in entanglements; clear and stand up
✓Train leglock defence as frequently as upper-body submission defence — the leg game is no longer optional
Типичные ошибки
!Ignoring the leg entanglement and focusing only on the heel/knee — the entanglement is the root problem; clear it
!Not understanding inside vs. outside position — outside knee position means you're the one being attacked
!Crossing your legs when defending — this gives the opponent control of both legs
!Bending the knee against a heel hook — straighten or at minimum keep it neutral; bending gives more rotational access
!Not boot-hiding immediately when caught in 50/50 or ashi garami — the boot must be automatic
!Pulling the leg straight out without clearing the entanglement — the opponent will simply re-enter
!Treating leglock defence as a white/blue belt concern only — the best grapplers in the world actively drill leglock defence

Boot Defence
ПодсемействоThe Boot Defence subfamily covers the technique of hiding the foot from the opponent's grip by curling the toes, pointing the foot, and tucking the heel behind the opponent's body or thigh. [1] The boot is the first-line defence against heel hooks and ankle locks — by preventing the opponent from accessing and controlling the foot, the submission cannot be applied. [1,2] The boot defence requires the defender to actively manage foot position throughout any leg entanglement, treating the foot like a hand that must be kept safe from grips. [2,3]

Hip Pressure Defence
ПодсемействоThe Hip Pressure Defence subfamily covers leg lock defence techniques where the defender drives their hips toward the opponent, reducing the space needed for the submission's rotational or extension mechanics. [1] Hip pressure defence works by closing the distance between the defender's hip and the opponent's controlling hands, which reduces the lever arm and consequently the force the opponent can generate on the joint. [1,2] Driving the hips forward is the primary defence against kneebars and a critical secondary defence against heel hooks. [2,3]

Leg Pummeling Defence
ПодсемействоThe Leg Pummeling Defence subfamily covers defensive techniques where the defender systematically frees their legs from the opponent's entanglement, working to remove the legs from positions that expose them to submission attacks. [1] Leg pummelling is the ground-equivalent of hand fighting in the clinch — it involves using the legs to swim inside and outside the opponent's leg control, clearing hooks and entanglements. [1,2] Effective leg pummelling is essential for escaping saddle, 50/50, and other leg entanglement positions that are the foundation of modern leg lock attacks. [2,3]

Заметки
Leg lock defense follows the Danaher principle: 'clear the knee line first, then address the grip.' If the attacker's hips are above your knee, you are in immediate danger. The boot (straightening the foot to prevent the heel hook grip) is the first-line defense. Never rotate away from a heel hook — always rotate into the pressure to relieve torque. (Danaher, Enter the System; Lachlan Giles instructionals)
Часто задаваемые вопросы
How do I defend against heel hooks and foot locks at the same time?
According to Dinu Bucalet, the key is to hide your heel by turning your whole leg and foot into your opponent's ribs rather than just turning your knee. This positioning makes it nearly impossible for them to catch your heel for either a straight foot lock or heel hook, regardless of whether your leg is on the same side or across their body.
What are the main defensive concepts I should focus on when caught in a leglock?
Dinu Bucalet emphasizes three core concepts: first, turn your heel in the right direction to hide your heel and Achilles; second, put weight and pressure on the leg being attacked; and third, work to undo your opponent's control by managing their grip and positioning.
When my opponent has me in a leglock, where should I apply pressure to escape?
Identify which direction you need to push based on your opponent's control—you may need to push up or in different directions. Dinu Bucalet notes that you should look for where their top leg is and apply pressure accordingly by controlling their grip either over or under, depending on the situation.
