ARMBAR FROM MOUNT
Armlock da Montada
Also known as: Mounted Armbar, Juji-Gatame from Mount
The armbar from mount is one of the canonical mount submissions and the natural follow-up to a defended cross-collar choke. Where the closed-guard armbar requires building an angle from underneath, the mounted armbar uses the dominant top position as the starting point — the leg swings from above rather than from below, gravity assists rather than resists, and the bottom player's defensive options are dramatically narrower.
The entry is established when the bottom player extends one arm upward to defend a choke or to push the attacker's body — typically a hand-fight against the cross-collar grip or a frame against the chest. The attacker traps the extended wrist with one hand, slides their hips to the trapped-arm side as they transition to S-mount, throws the free leg over the bottom player's head, and pivots backward to fall toward the bottom player's hips, completing the armbar with both legs across the body and the trapped arm held against the attacker's chest.
What makes the mounted armbar particularly devastating is its position within the three-attack mount chain (armbar, mounted triangle, arm triangle) that share the same S-mount setup. Any defensive response the bottom player chooses opens one of the other two attacks, which means the bottom player must defend all three threats simultaneously to escape. Roger Gracie's career featured this chain extensively, and the mounted armbar remains a top-five submission from mount at every level of IBJJF and ADCC competition.
Defensively the mounted armbar is escaped by preventing the arm from extending upward in the first place (keep both elbows tight to the centerline from the bottom of mount), by rolling toward the attacker as the leg swings over to disrupt the angle, or by stacking the attacker forward to compress the position before the fall completes. Once the attacker has fallen back to complete the armbar, the only options are tap-to-grip or attempting to hitch-hike the trapped arm out — both low-percentage at the highest level of competition.
KEY POINTS
- 01Set up the armbar with a cross-collar choke threat first; the choke forces the arm to extend.
- 02Trap the extended wrist with one hand, threading through if needed.
- 03Transition to S-mount, sliding hips to the trapped-arm side.
- 04Throw the free leg over the opponent's head as you pivot backward.
- 05Fall toward the opponent's hips with both legs across the body and the trapped arm clamped to your chest.
- 06Finish with hip extension; never pull only with the arms.
COMMON MISTAKES
- ✕Attempting the armbar without a choke setup first, giving the opponent no reason to extend the arm.
- ✕Failing to S-mount before throwing the leg over, leaving the angle square.
- ✕Falling back without trapping the wrist first, losing the arm during the fall.
- ✕Crossing the ankles after falling back, which weakens the knee pinch.
- ✕Pulling on the wrist instead of extending the hips to finish.
TRAINING DRILLS
- →Choke-to-armbar setup: from mount, drill the cross-collar grip that forces the arm to extend.
- →S-mount transition: 30 reps per side of the mount-to-S-mount slide.
- →Leg-throw-and-fall drill: combine the leg over the head with the backward fall.
- →Three-attack-chain drill: drill choke → armbar → triangle from a single mount entry.
- →Live mount rounds with the three-attack chain as the only allowed finishes.
