SAFETY: Belly Down Armbar from Lasso Guard targets the Elbow joint hyperextension and ulnar collateral ligament. Risk: Elbow hyperextension with ligament damage to the ulnar collateral ligament. Release immediately upon tap.
Attacking the belly down armbar from lasso guard leverages the pre-existing arm isolation that lasso control provides. The lassoed arm is already trapped by your shin and sleeve grip, eliminating the most challenging aspect of any armbar attack — separating a single arm from the opponent’s defensive framework. Your primary task is transitioning from the lasso configuration into an armbar position, then rotating belly down to apply maximum finishing pressure while denying common escape routes. The transition timing is critical: attack when the opponent is focused on sweep defense, and they will not recognize the submission threat until the rotation is already underway.

Key Attacking Principles
What are the key principles for executing Belly Down Armbar from Lasso Guard?
- Maintain unbroken sleeve control throughout the entire transition from lasso guard to belly down armbar — losing the grip at any point allows the arm to retract
- Use sweep threats as setup deception to force the opponent into weight-commitment patterns that expose the arm for the armbar entry
- Break the opponent’s posture fully with the lasso tension before initiating the leg swing, as an upright opponent can resist the transition
- Pinch your knees tightly around the arm during and after the belly down rotation to prevent any gap that allows extraction or hitchhiker escapes
- Apply extension progressively once belly down — the mechanical advantage is extreme and the finish requires control rather than explosive force
- Time the lasso release precisely: only after both legs are secured around the arm in the armbar configuration, never before
Prerequisites
What do you need before attempting Belly Down Armbar from Lasso Guard?
- Established deep lasso guard with shin threaded across the opponent’s tricep and tight sleeve grip on the target arm
- Opponent’s posture broken or compromised by sustained lasso tension pulling the trapped arm forward and down
- Non-lasso leg free and positioned to swing over the opponent’s head or chest for the armbar transition
- Hips angled perpendicular to the opponent to create the rotational angle needed for the belly down transition
- Secondary grip on collar, pants, or belt to assist with posture control during the initial phase
Execution Steps
How do you execute Belly Down Armbar from Lasso Guard step by step?
- Establish deep lasso with maximum tension: Thread your shin deeply across the opponent’s tricep, past the elbow crease toward the shoulder. Pull the sleeve grip aggressively toward your chest while extending the lasso leg to create maximum leverage against their shoulder joint. Your hips should be angled perpendicular to the opponent’s centerline. (Timing: 0-3 seconds)
- Break opponent’s posture with lasso pull: Use the lasso tension combined with your non-lasso foot posting on their hip or bicep to pull the opponent’s upper body forward and down. Their weight should shift onto the trapped arm, making it load-bearing and difficult to retract. Confirm their posture is broken before proceeding. (Timing: 2-4 seconds)
- Create angle and initiate leg swing: Remove your non-lasso foot from the hip and begin swinging it over the opponent’s head or across their face. Simultaneously hip-escape slightly away from the lasso side to create the rotational angle needed for the armbar. Your hips should move underneath the opponent’s trapped arm as the leg swings over. (Timing: 1-2 seconds)
- Secure armbar position with both legs: Land the swinging leg across the opponent’s neck or upper back while your lasso leg maintains its position across the arm. Squeeze both knees together tightly to clamp the arm between your thighs. The arm should be pinned with the elbow joint aligned against your hip crease for the finish. (Timing: 1-2 seconds)
- Release lasso and transition to wrist control: Only now release the lasso threading by withdrawing your shin from across the arm. Immediately switch to two-handed wrist control, gripping the opponent’s wrist with both hands and pulling it tight to your chest. Your legs maintain the clamp around the arm throughout this grip transition. (Timing: 1-2 seconds)
- Rotate to belly down position: Roll toward the opponent’s legs while maintaining wrist control and knee squeeze. Your chest should rotate to face the mat as your body weight transfers onto the opponent’s back and trapped arm. Keep the wrist pulled tight against your chest throughout the rotation to prevent any slack in the arm. (Timing: 1-3 seconds)
- Settle weight and establish base: Once belly down, spread your legs slightly for base and press your hips down to pin the opponent flat. Your body weight should be centered over the trapped arm. Ensure the elbow joint remains aligned against your hip crease and the opponent cannot create any rotational movement. (Timing: 1-2 seconds)
- Apply controlled extension for the finish: Lift the wrist slowly and progressively by arching your back and raising your hips while keeping the arm pinned at the elbow against your pelvis. Apply extension gradually — the mechanical advantage is extreme. Monitor for tap signals continuously and release immediately upon any indication of submission. (Timing: 2-5 seconds, progressive)

Opponent Defenses
How might your opponent defend against Belly Down Armbar from Lasso Guard?
- Opponent stacks weight forward and drives into you before rotation completes (Effectiveness: High) - Your Response: Switch to an overhead sweep using their forward momentum, or abandon the armbar and transition to a triangle or omoplata entry that capitalizes on their broken posture and committed weight → Leads to Lasso Guard
- Opponent strips the sleeve grip and retracts arm during the lasso-to-armbar transition window (Effectiveness: Medium) - Your Response: Immediately re-establish lasso control or transition to spider guard on the same arm. If the arm is partially free, redirect to a wrist-controlled armbar without the lasso, using your legs to maintain the arm position → Leads to Lasso Guard
- Opponent postures up aggressively to break lasso tension before any attack develops (Effectiveness: Medium) - Your Response: Use the upright posture as a sweep opportunity — their elevated center of gravity makes them vulnerable to sickle sweeps and off-balancing attacks that expose the arm for future attempts → Leads to Lasso Guard
- Opponent clasps hands together or grabs own wrist to prevent arm extension once in belly down position (Effectiveness: Low) - Your Response: Bridge your hips to change the angle and peel the grip. Alternatively, switch to a two-on-one wrist peel or transition to a triangle by releasing one leg and threading it under the defending arm → Leads to Closed Guard
