X-Guard

Last updated: June 13, 2026

What is the X-guard?

Open guards are the family of bottom positions where a grappler uses the legs, rather than a closed lock around the body, to control distance and an opponent. The X-guard belongs to this family, but it places the bottom grappler directly under the opponent’s center of gravity instead of out in front of them. The name comes from the shape the legs make: one foot hooks behind the opponent’s knee while the other presses against the hip, crossing into a rough X around a single leg.

Marcelo Garcia popularized the position in the early 2000s, and it has since become a standard tool from the recreational level up to world championship finals. It works in both gi and no-gi. Because the bottom grappler sits beneath the opponent’s base, many ordinary guard passes lose their footing, which is part of why the position has lasted.

How the X-guard works

The whole position runs on balance. By sitting under the opponent and spreading the legs in opposite directions, the bottom grappler can tip the standing person’s weight past their own feet, a concept borrowed from judo called kuzushi, or balance-breaking. Small adjustments from underneath produce large reactions on top, since the opponent is balanced on a narrow base.

From there, the payoff is the sweep. A grappler in the X-guard can off-balance an opponent forward, backward, or to either side, then come up on top as the opponent stumbles. Modern players also treat the X-guard as a doorway to leg attacks, sliding into related entanglements to threaten the lower body. One thing worth knowing: the X-guard itself is built for sweeping and control rather than finishing. Direct submissions usually come after a transition into a tighter leg-attack position rather than from the X-guard on its own.

X-guard vs single leg X

This is the comparison people search for most, because the two positions look alike and share a name. The single leg X, often shortened to SLX and also called ashi garami, isolates one of the opponent’s legs with a different leg configuration and sits slightly more to the side rather than fully underneath. It is usually described as a close cousin or a subset of the X-guard, and grapplers move between the two constantly during a roll.

	X-guard	Single leg X (SLX)
Leg position	Both legs cross around one of the opponent’s legs, fully underneath	Wraps one leg in a more upright, ankle-focused setup, slightly to the side
Main goal	Off-balancing and sweeping	Sweeping plus direct leg-lock entries
Best known for	Control from directly under the opponent	Ankle locks and heel hooks, especially in no-gi
Relationship	The broader position	A specialized branch of the X-guard family

A simple way to keep them straight: the X-guard is the control-and-sweep position, while the single leg X is the leg-lock-friendly relative that grew with the modern lower-body game.

Types of X-guard

Grapplers have developed several configurations, all of which keep some version of the X shape with the legs. The differences come down to where the hooks sit and how much of the opponent’s leg gets controlled.

Variation	What sets it apart
Standard (straight) X	The original. One leg hooks behind the knee, the other controls the hip, with the opponent’s leg trapped over the shoulder.
Reverse X	The leg positions switch so both hooks work the hip. It rose with the modern leg-lock game and opens entries to leg attacks.
Low X	Trades hip control for control of the foot at the end of the leg, giving a longer lever on the opponent.
Single leg X (SLX)	Isolates one leg in a more upright position. The most common cousin of the standard X.
Low single leg X	Both legs hook in an X on the opponent’s ankle. Often used to stall fast guard passers in no-gi.

Common misconceptions

A few ideas about the X-guard come up often and are worth correcting. The first is that it is a beginner move. In practice, most grapplers meet the position around blue belt, once they are comfortable with open guard and off-balancing. The second is that the X-guard is mainly a submission position. It is built first for sweeping and control, and submissions tend to come from positions you reach after the X-guard, not from it directly. The third is that it only belongs in no-gi or leg-lock grappling. It started in the gi with Marcelo Garcia and still works there, even though the modern leg-lock scene has given it a second life in no-gi.

Frequently Asked Questions

Is the X-guard good for beginners?

It is usually taught after the fundamentals, around blue belt, because it depends on comfortable open-guard movement and timing. A beginner can start learning the shape earlier, but it tends to click once basic balance-breaking makes sense.

Does the X-guard work in MMA?

It can, though it carries more risk than in grappling. Because the bottom person is underneath and controlling a leg, the opponent’s hands are free to strike, so fighters use it carefully and tend to move quickly toward a sweep.

Who invented the X-guard?

Its exact origin is unclear, but Marcelo Garcia is credited with popularizing it at the highest levels in the early 2000s, and his name is still attached to the position.

Can you submit someone directly from the X-guard?

Rarely. The position is built for sweeping and control. Most submissions, especially leg locks, come after transitioning into a tighter position, such as the single leg X.

Is the X-guard legal in competition?

The position itself is legal across the major rulesets. The leg attacks launched from it are what vary: heel hooks and knee reaping are restricted under IBJJF rules for most belt levels, while no-gi rulesets such as ADCC allow far more.
