The Mounted Crucifix Entry is an advanced transition that capitalizes on the arm isolation opportunities inherent in S Mount to establish one of the most dominant control positions in Brazilian Jiu-Jitsu. This technique transforms the attacking angle of S Mount into complete upper body control by threading your legs over both of the opponent’s arms, effectively removing their primary defensive tools.
From a strategic standpoint, the mounted crucifix entry represents the natural evolution of S Mount attacking sequences. When opponents successfully defend armbar attempts by bending their arms or bringing their free arm across to defend, they inadvertently expose themselves to crucifix control. The entry exploits the defensive arm positioning that often follows failed submission attempts, turning opponent defense into opportunity for advancement.
The technical requirements for this entry demand precise timing and weight distribution. You must maintain sufficient mount pressure to prevent bridging escapes while creating the space needed to thread your leg over the opponent’s second arm. This balance between control and mobility distinguishes successful crucifix entries from failed attempts that result in positional loss. The transition requires reading opponent reactions and capitalizing on their defensive movements rather than forcing the position against strong resistance.

Playing as Attacker
Key Principles
-
Maintain S Mount stability throughout the entire transition - never sacrifice base for the crucifix entry
-
Capitalize on opponent’s defensive arm positioning rather than forcing arms into vulnerable positions
-
Use hip pressure and weight shifts to create space for leg threading without compromising control
-
Thread legs sequentially - secure one arm completely before attempting to isolate the second
-
Keep knees tight immediately after establishing arm traps to prevent early extraction
-
The crucifix is earned through positional pressure, not athletic explosion
-
Recognize when opponent defense is too strong and return to standard S Mount attacks instead
Execution Steps
-
Secure S Mount control: Establish tight S Mount with your hip bone pressed firmly into opponent’s near shoulder. Your near l…
-
Identify arm exposure: Watch for opponent’s far arm to cross their centerline - this commonly occurs when they attempt to p…
-
Shift weight forward: Transfer your weight slightly forward onto your chest and posting arm, reducing pressure on your sea…
-
Thread leg over second arm: Lift your far leg (the one crossing their torso) and thread it over opponent’s exposed far arm, posi…
-
Clamp knees together: Immediately squeeze both knees together once the second arm is trapped, creating a vice-like pinch o…
-
Settle weight and establish control: Lower your hips back down while maintaining the knee clamp, redistributing weight forward onto oppon…
Common Mistakes
-
Attempting crucifix entry before establishing solid S Mount control
- Consequence: Opponent escapes mount entirely during the transition attempt due to unstable base and insufficient pressure
- Correction: Spend additional time consolidating S Mount with tight hip-to-shoulder pressure before attempting any crucifix transition
-
Lifting leg too high during thread-over creating excessive space
- Consequence: Opponent uses the space to hip escape or extract their already-trapped arm before second arm is secured
- Correction: Use hip rotation to slide leg over rather than lifting high, keeping body low and connected throughout transition
-
Failing to squeeze knees together immediately after trapping second arm
- Consequence: Opponent extracts one or both arms before crucifix control is established, wasting the entry opportunity
- Correction: Make knee squeeze an automatic reaction that occurs simultaneously with leg landing, treating it as one combined motion
Playing as Defender
Key Principles
-
Keep far arm tight to your body at all times - never reach across your centerline while defending S Mount submissions
-
Time defensive explosions to the attacker’s weight shift, when their base is most compromised during leg threading
-
Frame against opponent’s hip with your free hand rather than gripping your own collar, which crosses the arm into danger
-
Prioritize preventing the second arm trap over escaping S Mount - one trapped arm is survivable, two is catastrophic
-
Use hip escape toward the opponent’s legs during their weight shift to create distance and disrupt the threading angle
-
Bridge toward the leg being threaded, not away from it, to collapse the space the attacker needs for the motion
-
If both arms get trapped, immediately shift to mounted crucifix escape protocols rather than wasting energy on prevention
Recognition Cues
-
Opponent shifts weight forward onto their chest and posting arm while in S Mount, reducing seated pressure on your torso
-
Opponent’s far leg (the one crossing your torso) lifts or rotates, indicating they are beginning the threading motion over your arm
-
Opponent releases wrist control on your near arm to post or stabilize, freeing their hands for the transition
-
Opponent’s hips rotate perpendicular to your body, creating the angle needed to slide their leg over your far arm
-
You feel reduced pressure from their seated position as they elevate to create space for the leg movement
Defensive Options
-
Explosive bridge toward the threading leg during weight shift - When: The instant you feel opponent shift weight forward and begin lifting their far leg off your torso
-
Retract far arm tight to body and frame against opponent’s hip - When: Preemptively whenever you recognize S Mount position, before any crucifix attempt begins
-
Hip escape toward opponent’s legs combined with shoulder turn during weight shift - When: When opponent commits to the forward weight shift and begins rotating hips for the leg thread
Position Integration
The Mounted Crucifix Entry serves as a critical link between S Mount attacking sequences and the submission-rich mounted crucifix position. It represents the natural progression when armbar defenses succeed but create arm exposure. This transition exemplifies the principle of using opponent defense against them - their protective arm movements become the pathway to worse positions. The technique integrates with the broader mount attack system by providing an alternative when primary submissions are defended, and it connects to the crucifix submission ecosystem including neck attacks and armbar chains. Understanding this entry expands your S Mount game from single-submission focused to a complete attacking system with positional advancement options.
