What is Hooks?

A hook is a curved attachment — a foot wrapped behind a knee, a hand threaded under an armpit, an instep tucked inside a thigh. Hooks are the attachment mechanic of BJJ. Unlike grips, which rely on grabbing and squeezing, hooks use the natural curve of feet, hands, and limbs to wrap around the opponent’s body and create connection points that resist removal through their geometry. You cannot simply pull a hook off by yanking — you must change the angle, peel it away, or create enough space to disengage the curve. This geometric resilience makes hooks one of the most reliable control mechanisms in grappling.

Hooks appear everywhere. The butterfly guard is defined by feet hooked under the opponent’s thighs. Back control requires heel hooks inside the opponent’s thighs. The De La Riva guard wraps a foot behind the opponent’s lead knee. The underhook threads an arm under the opponent’s armpit and curves upward behind the shoulder. The overhook wraps over the opponent’s arm and curves downward to trap it. In each case, the hook creates a persistent connection that the opponent must actively work to remove, buying the hooking player time, control, and options.

What distinguishes hooks from other attachment methods is their passive retention quality. A grip requires constant muscular effort to maintain — relax your hand and you lose the grip. A hook, once set, tends to stay in place even with minimal active effort because the curved geometry naturally resists linear pulling forces. This makes hooks exceptionally energy-efficient. A butterfly hook sitting passively under the opponent’s thigh maintains its position until the opponent specifically addresses it. This passive retention allows the hooking player to focus attention and energy on other tasks — setting up sweeps, establishing grips, or transitioning — while the hooks quietly maintain the fundamental connection.

Building Blocks

• Curve the hooking limb around the target to create geometric retention that resists linear removal
• Set hooks early during transitions before the opponent can establish defensive barriers
• Use the instep and heel for foot hooks — the curve of the foot naturally wraps around limbs
• Thread arm hooks deep enough that the curved portion passes fully behind the target
• Maintain active hook pressure (pulling or lifting) to amplify the passive retention
• Layer multiple hooks to create redundant attachment that survives one hook being stripped
• Recognize that hook removal requires angle change, not just pulling — defend hooks by changing the angle
• Combine hooks with grips to create attachment systems that are stronger than either alone
• Keep hooks light and responsive rather than rigid — a mobile hook can reattach after being partially stripped

Prerequisites

Foot Hook Placement: The ability to set foot hooks with precision — instep behind the knee for back control, foot inside the thigh for butterfly guard, heel on the hip for open guard retention. Proper foot hook placement means the curved portion of the foot wraps fully around the target, creating geometric retention that resists the opponent’s stripping attempts.

Underhook Threading: Threading the arm under the opponent’s armpit and curving upward behind the shoulder blade. A deep underhook with the elbow past the opponent’s centerline provides powerful directional control — the ability to steer the opponent’s upper body. Shallow underhooks that stop at the armpit provide weak attachment and are easily countered with a whizzer.

Overhook Control: Wrapping the arm over the opponent’s arm and curving downward to trap it against your body. The overhook (whizzer) counters the underhook and creates its own control opportunities including back takes and sweeps. Effective overhooks press the elbow tight against the ribs to prevent the opponent from withdrawing the trapped arm.

Hook Depth Management: Controlling how deep hooks are inserted to balance retention with mobility. Deep butterfly hooks provide maximum sweep leverage but limit your own hip mobility. Shallow hooks allow quick transitions but can be stripped easily. Learning to modulate hook depth based on the tactical situation is a key skill.

Hook Reattachment: When a hook is partially stripped, quickly reattaching it before the opponent can capitalize on the loss of connection. This requires keeping the hooking limb light and responsive rather than rigid, so it can flow back into position along a new angle when the original attachment is disrupted.

Dual Hook Coordination: Managing two hooks simultaneously — both butterfly hooks, both back control hooks, or an underhook-overhook combination. When both hooks work together, they create a control system where stripping one hook often exposes the opponent to the other. This creates a dilemma that is harder to solve than a single attachment point.

Hook-Based Elevation: Using hooked feet to elevate the opponent’s body weight for sweeps, off-balancing, and guard transitions. The butterfly hook elevates the thigh, the X-guard hooks elevate the entire leg, and the De La Riva hook controls the opponent’s balance point. Understanding how hooks create upward force is essential for sweep mechanics.

Hook Defense and Stripping: Recognizing when the opponent has established hooks and knowing how to remove them. Hook stripping requires angle changes — pushing the hooking foot sideways rather than trying to pull it straight out, or swimming past an underhook rather than trying to peel it off with strength.

Where to Apply

Butterfly Guard: Both feet hooked under the opponent’s thighs create the defining attachment of butterfly guard. These hooks provide upward elevation for sweeps, distance control to prevent smashing passes, and the ability to redirect the opponent’s weight laterally for off-balancing.

Back Control: Both heels hooked inside the opponent’s inner thighs are the primary retention mechanism for back control. The hooks prevent the opponent from sliding down and escaping. Losing both hooks generally means losing the position. Body triangle is an alternative when hooks are stripped.

De La Riva Guard: The De La Riva hook wraps the outside foot behind the opponent’s lead knee, curving around the leg to control their base and balance. This single hook is the foundation of the entire guard system, providing the attachment from which sweeps, back takes, and berimbolo entries are launched.

Half Guard: From bottom half guard, the underhook on the near side is the single most important hook. A deep underhook allows the bottom player to come to the knees, take the back, or execute sweeps. Without the underhook, the bottom half guard player is flat and defensive.

Clinch: Underhooks and overhooks define the clinch battle. An underhook provides steering control and takedown entries. An overhook (whizzer) defends against the underhook and creates its own back take and throw opportunities. The clinch is fundamentally a hook fight.

X-Guard: Both legs hook the opponent’s lead leg — one foot behind the knee, one foot on the hip — creating an X-shaped hook configuration that elevates the entire leg and controls the opponent’s base from underneath. The dual hook creates powerful sweep leverage.

Single Leg X-Guard: One foot hooks behind the opponent’s knee while the legs control the shin, creating a hook-based entanglement on a single leg. This hook configuration enables technical stand-ups, sweep entries, and transitions to leg lock positions.

Reverse De La Riva Guard: The inside foot hooks behind the opponent’s lead knee from the inside, inverting the standard DLR hook direction. This reverse hook provides a different angle of base disruption and enables bolo entries and outside passing defense.

Open Guard: Feet hooked on hips, biceps, or inside thighs provide the retention connections that keep the passer engaged. Open guard without hooks becomes pure distance management — adding hooks gives the guard player active control over the passer’s positioning.

Turtle: The attacking player attempts to insert hooks (heels inside the thighs) to convert turtle control into back control. The defending player pinches elbows and knees to prevent hook insertion. The hook insertion battle is the defining contest from turtle.

Dogfight Position: The dogfight emerges from half guard when both players have underhooks and come to their knees. The underhook depth and angle determine who gets the back take. The deeper underhook usually wins the dogfight exchange.

Crab Ride: Hooks behind the opponent’s knees from the back-side create the crab ride attachment. These hooks control the opponent’s ability to stand or turn while providing entries to leg locks and back takes.

Spider Guard: Feet hooked on the opponent’s biceps combined with sleeve grips create the spider guard attachment system. The foot hooks on the biceps control the opponent’s arm positioning and posture, enabling sweeps and triangle entries.

Standing Position: In standing grappling, foot hooks behind the opponent’s heel or ankle are used for reaps and trips. Arm hooks (underhooks) from standing provide the attachment needed for body lock takedowns and duck-under entries.

How to Apply

1. Identify what you need to attach to on the opponent’s body: Determine the target: legs for guard hooks, inner thighs for back control hooks, armpit for underhooks, arm for overhooks. The target determines which type of hook and which limb to use.
2. Assess whether the opponent is defending the hook entry point: Check if the opponent’s elbows are tight (preventing underhooks), knees are pinched (preventing butterfly hooks), or arms are blocking (preventing back control hooks). If defended, use a distraction or angle change to open the entry.
3. Thread the hook with enough depth for geometric retention: Insert the hook past the point where it wraps around the target. A shallow hook that does not complete the curve can be stripped easily. Drive the foot, hand, or arm deep enough that the curve creates a natural lock around the target structure.
4. Activate the hook with directional pressure: Once set, apply active pressure in the direction you want to control: lift with butterfly hooks for elevation, pull with back control hooks for retention, drive with the underhook for steering. Passive hooks maintain connection but active hooks create control.
5. Establish a complementary second hook or grip: One hook provides attachment; two hooks create a dilemma. Set the second butterfly hook, establish a grip alongside the underhook, or insert the second back control hook. Redundant attachment survives one hook being stripped.
6. Monitor hook integrity and respond to stripping attempts: Feel for the opponent working to remove your hooks. When you sense a hook being stripped, either re-set it from a new angle, activate a backup hook or grip, or use the moment of their focus on hook stripping to attack or transition.
7. Use the hook connection to execute your technique: Hooks are tools for sweeps, back takes, guard retention, and position maintenance. Once hooks are set and secure, execute the technique they enable — butterfly sweep, back take from turtle, De La Riva sweep, or underhook to single leg.
8. Release or transition hooks as the position changes: Hooks that served one position may hinder the next. Release hooks that are no longer useful and re-set new hooks appropriate to the emerging position. Do not cling to hooks from a previous position when the situation has changed.

Mistakes to Avoid

• Mistake: Setting hooks too shallow so they do not complete the curve around the target
  • Consequence: Shallow hooks are easily stripped because they do not have geometric retention. A butterfly hook with only the toes touching the thigh can be kicked off with a simple knee pinch. An underhook that stops at the armpit is countered by a basic whizzer.
  • Correction: Drive hooks deep. The foot should wrap past the knee line in butterfly guard, the arm should thread past the opponent’s centerline in an underhook, and the heel should pass fully inside the thigh for back control. The curve must complete for retention to work.
• Mistake: Making hooks too rigid instead of keeping them responsive and mobile
  • Consequence: Rigid hooks break under sudden angle changes. When the opponent explosively changes direction, a stiff hook snaps out of position and cannot reattach. Rigidity also prevents the hook from following the opponent’s movement.
  • Correction: Maintain active tension rather than locked rigidity. Keep the hooking limb firm enough to maintain connection but flexible enough to follow the opponent’s movement and re-curve around the target from new angles when displaced.
• Mistake: Failing to set hooks during transitions when gaps are open
  • Consequence: Hooks are easiest to insert during movement when the opponent’s limbs are not set in defensive positions. Missing these windows means having to fight for hook insertion against a settled, defending opponent, which is far more difficult.
  • Correction: Develop awareness of transitional moments — when the opponent stands up, turns, or shifts weight — as hook insertion opportunities. Train to insert hooks reflexively during scrambles and transitions rather than waiting for static positions.
• Mistake: Relying on a single hook without establishing backup attachment
  • Consequence: A single hook is a single point of failure. When it gets stripped, all connection is lost and the position collapses. Back control with one hook, butterfly guard with one hook, or a single underhook without grip support are all fragile.
  • Correction: Always work toward dual hooks or hook-plus-grip combinations. Set the second butterfly hook, establish both back control hooks, or pair the underhook with a collar grip. Redundant attachment provides resilience.
• Mistake: Trying to strip opponent’s hooks by pulling straight out instead of changing the angle
  • Consequence: Hooks resist linear removal by design — the curve catches on the target when pulled directly. Yanking at a hook wastes energy and often fails because you are fighting against the geometry.
  • Correction: Strip hooks by changing the angle. Push the hooking foot sideways off the thigh, swim your arm past the underhook laterally, or rotate your body to change the angle of the curve. Hooks resist straight pulls but are vulnerable to angular displacement.
• Mistake: Setting hooks in the wrong direction for the intended technique
  • Consequence: A butterfly hook angled inward provides no sweep leverage outward. An underhook threaded at the wrong angle does not allow a back take. The hook is set but provides no tactical value because its directional force is misaligned with the technique.
  • Correction: Align hook direction with technique direction. Angle butterfly hooks in the sweep direction, thread underhooks toward the back for back takes, and set DLR hooks to control the angle you want to sweep toward. The hook should point where you want the opponent to go.
• Mistake: Neglecting foot position — using the top of the foot instead of the instep or heel
  • Consequence: The top of the foot has no natural curve for wrapping. Using it for hooks results in weak attachment that slides off under any pressure. The opponent can easily clear a foot that is not properly curved around the target.
  • Correction: Use the instep (inside curve of the foot) for hooks that wrap behind legs and the heel for hooks that need to dig into inner thighs. The natural curve of these foot surfaces creates the geometric retention that makes hooks effective.

How to Practice

Hook Insertion Speed Drills (Focus: Developing the timing and speed needed to set hooks during the brief windows that appear during transitions. Builds the reflexive hook insertion that experienced grapplers perform without conscious thought.) Partner moves through various positions while the practitioner focuses on inserting hooks as quickly as possible during transitional moments. No submissions or sweeps — just repeated hook insertion and release to build reflexive hook setting during movement.

Hook Retention Under Resistance (Focus: Building the sensitivity to feel hook stripping attempts early and developing the reflexive responses that maintain hook attachment. Teaches the difference between rigid hook holding (bad) and responsive hook maintenance (good).) Start with hooks established (butterfly guard, back control, DLR) and have the partner work progressively harder to strip them. Focus on maintaining hooks through micro-adjustments, re-curving when partially stripped, and using active hook pressure to resist removal.

Hook Stripping Practice (Focus: Understanding hooks from the defensive perspective — how to recognize, prevent, and remove the opponent’s hooks efficiently. Develops the angular stripping mechanics that defeat geometric retention.) Partner establishes various hooks and the practitioner works to strip them using angle changes rather than strength. Practice clearing butterfly hooks with knee pinches, stripping underhooks with swim moves, and removing back control hooks with foot peel sequences.

Underhook-Overhook Flow Drilling (Focus: Developing fluency in the arm hook battle that defines clinch work and half guard. Builds the automatic threading and countering of arm hooks that separates experienced grapplers from beginners.) Partners continuously alternate between underhook and overhook positions, flowing between attack and defense. One partner threads the underhook, the other counters with an overhook, then they switch. Practice from standing, kneeling, and half guard positions.

Guard-Specific Hook Drilling (Focus: Building position-specific hook competence. Each guard uses hooks differently, and drilling the specific hook insertion, depth, angle, and pressure for each guard develops the nuanced understanding that makes each guard functional.) Practice the hook mechanics specific to individual guard types: butterfly hooks for butterfly guard, DLR hook for De La Riva, spider hooks for spider guard, X-guard hooks for X-guard. Drill each guard’s hooks independently with progressive resistance.

Back Control Hook Battles (Focus: Building competence in the most consequential hook battle in BJJ — back control hook retention versus clearing. Both skills are essential and this drill develops them simultaneously.) Positional sparring starting from back control where the attacker tries to maintain both hooks while the defender tries to clear them. The round resets when hooks are fully cleared or maintained for 60 seconds. Develops the specific hook retention and stripping skills for back control.

Related Principles

• Grips (Complementary): Hooks and grips are the two primary attachment methods in BJJ. Grips provide active, grip-dependent connection while hooks provide passive, geometry-dependent connection. The strongest attachment systems combine both — a butterfly hook under the thigh paired with a collar grip creates far more control than either alone.
• Connection Principles (Extension): Hooks are one of the primary mechanisms for establishing and maintaining connection with the opponent. Connection principles provide the strategic framework for when and where to hook, while hooks provide the physical mechanics for executing that connection.
• Base (Complementary): Hooks disrupt the opponent’s base by creating attachment points that restrict their movement and weight distribution. The butterfly hook under the thigh lifts one of the opponent’s base points, compromising their stability. Understanding base reveals where hooks are most disruptive.
• Kuzushi (Complementary): Hooks provide the attachment points from which off-balancing forces are applied. The butterfly hook elevates, the De La Riva hook redirects, and the underhook steers — all creating the kuzushi (off-balancing) needed for sweeps and takedowns.
• Control Maintenance (Extension): Hooks are a primary tool for maintaining control over time. Their passive retention quality means hooks maintain connection with minimal energy expenditure, making them ideal for sustained control situations like back control and guard retention.
• Distance Control (Complementary): Hooks establish a connection that controls distance from within. Unlike frames which push away or grips which pull close, hooks maintain a specific distance relationship — close enough to control but positioned to prevent the opponent from either closing or creating more distance.
• Defensive Concepts (Complementary): From a defensive perspective, understanding hooks means knowing how to prevent their insertion and how to strip them once established. Keeping elbows tight prevents underhooks, pinching knees prevents butterfly hooks, and controlling the opponent’s feet prevents back control hooks.
• Dominant Angles (Complementary): Hooks often create angular advantages. An underhook from half guard creates an angle to the opponent’s back. A De La Riva hook controls the opponent’s lead leg angle. The directional control provided by hooks enables the angular superiority needed for sweeps and passes.
• Escape Fundamentals (Complementary): Escaping positions often requires stripping the opponent’s hooks — removing back control hooks to escape back mount, clearing butterfly hooks to pass guard, or swimming past underhooks to recover position. Hook stripping is a core escape skill.
• Energy Conservation (Complementary): Hooks are among the most energy-efficient control mechanisms in BJJ because their geometric retention works passively. A hook that is set correctly maintains its position without constant muscular effort, making hooks ideal for long matches and competition.
• Levers (Prerequisite): Hooks function as lever arms. The butterfly hook uses the thigh as a lever to elevate the opponent’s weight with the hip as fulcrum. The underhook uses the arm as a lever to steer the opponent’s upper body. Lever mechanics explain why hook depth affects power.
