Overview

The Standard S-Mount positions one leg swung up with the foot alongside the opponent's head, the other knee remaining by the hip, with the top fighter's hips angled to create the S-shape. [1] The standard S-mount provides immediate armbar access β€” the top fighter can fall back for the armbar with the head-side leg already in position to clamp over the face. [1],[2] The S-mount also provides submissions options including the mounted triangle and wrist locks. [2],[3]

Biomechanical Mechanism

Primary Action β€” Gravity-assisted top control β€” body weight pins the opponent's torso to the ground
Joints Involved β€” Attacker's hips (heavy base), knees (clamped for ride control), opponent's spine (pinned)
Force Vector β€” Downward β€” gravity plus active hip pressure maximises control and submission opportunities
Positional Mechanic β€” High mount raises the centre of gravity above the opponent's shoulder line, isolating their arms for attacks

Position & Entry

From guard pass completion β€” After passing the guard, establish mount by placing knees on either side of the opponent's torso
From sweep β€” Complete a sweep from guard and land directly in mount position on top
From side control (knee slide) β€” From side control, slide the knee across the opponent's belly and settle into mount

Variants

Low mount β€” hips heavy on the opponent's belly, grapevines in for stability
High mount β€” knees under the armpits, arms isolated for submissions
S-mount β€” one knee high under the armpit, other leg across for arm attacks
Technical mount β€” one leg hooked, one knee posted, modified for back-take transitions

Training Notes

βœ“Standard S-mount execution: from high mount, walk one knee past the opponent's shoulder until it reaches beside their head, post the opposite foot near their hip, angle the body into the 'S' curve, and control the near arm (Danaher, Mount Attacks, 2020)
βœ“Step 1: from high mount, choose which arm to attack β€” climb the corresponding knee past the shoulder
βœ“Step 2: the attacking-side knee advances until it presses against the opponent's head/ear
βœ“Step 3: the opposite foot posts on the mat near the opponent's hip for base
βœ“Step 4: angle the body to form the 'S' shape β€” the torso curves from head to hip
βœ“Step 5: control the near arm: grip the wrist or bicep of the arm you intend to armbar
βœ“Step 6: from here, fall back for the armbar: swing the far leg over the head and extend the hips for the finish
βœ“The S-mount is the last position before the armbar: it should feel like the finish is inevitable from here
βœ“Drill: from mount, climb to S-mount and finish the armbar β€” 5 reps per side

Common Mistakes

!Not advancing the knee far enough past the shoulder β€” the knee must reach the head for proper S-mount
!Posting the foot too far from the opponent β€” keep the base foot close for stability
!Not controlling the arm before falling back for the armbar β€” the arm must be gripped before committing
!Falling back for the armbar without pinching the knees β€” the knees must squeeze the arm during the armbar
!Rushing through S-mount without establishing control β€” take a moment to secure the position
!Not angling the body into the 'S' shape β€” the curve is what creates the control dynamic
!Only training S-mount on one side β€” develop the position on both sides

Frequently Asked Questions

When should I use S-mount versus technical mount?

Coach Brian emphasizes that S-mount works best when your opponent is flat on their backβ€”tuck your leg in tight. Use technical mount when your opponent is on their side, as S-mount positioning on a turned opponent compromises your balance and makes you vulnerable to escape.

How do I prevent my opponent from capturing my leg in S-mount?

Keep your foot positioned to prevent your opponent's frame escapeβ€”if your leg hangs down, they can capture it. By positioning your foot correctly, you make it much harder for them to shrimp or escape, even though some movement is still possible.

What's the key to securing S-mount position?

Coach Brian stresses that in S-mount, you want to be tucked under your opponent's elbow with good control, using your toe in the back for stability. This tight positioning gives you really good control and sets up submissions like the armbar.
