Mount: A White Belt's Biomechanical Guide

1. From a guard pass (e.g., knee-slice-pass), establish a strong chest-to-chest connection with the opponent on their back.
2. Sit your hips down, bringing your knees towards the mat on either side of their torso, aiming for a hip angle of approximately 90 degrees relative to their body.
3. Secure a "grapevine" by placing your shins across the outside of their thighs, with your feet flexed and toes pointed away from your body.
4. Maintain a wide base, with your knees spread wider than your opponent's hips to prevent them from bridging effectively.
5. Place your weight forward onto your chest and shoulders, driving your hips down towards the mat.
6. Secure "high hooks" by digging your feet into the mat behind their hips, allowing you to pull them forward and control their base.
7. Keep your elbows tucked in close to your body to prevent arm-based submissions and maintain upper body tightness.

• Spreading knees too wide: This can overextend the knee joint ligaments (MCL/LCL), leading to tears. The correct movement is to keep knees slightly wider than the opponent's hips, not excessively wide.
• Letting hips fall back: This relieves pressure and allows the opponent to escape by bridging or turning. The correct movement is to actively drive hips forward and down.
• Allowing opponent to frame with forearms inside your knees: This creates space for them to shrimp or bridge. The correct movement is to keep shins across their thighs (grapevine) and maintain tight knee control.

1. Solo drilling: Practice sitting into mount from a stable top position, focusing on hip angle and grapevine (50 reps).
2. Partner drill (no resistance): Practice transitioning to mount and holding for 10 seconds, focusing on base and weight distribution (20 reps).
3. Partner drill (25% resistance): Opponent lightly resists movement into mount. Focus on maintaining position and base (20 reps).
4. Partner drill (50% resistance): Opponent actively tries to prevent mount or escape once mounted. Focus on hip control and weight transfer (20 reps).
5. Partner drill (75% resistance): Opponent attempts to escape and counter from mount. Focus on maintaining control and transitioning to submissions (15 reps).
6. Live rolling (90-100% resistance): Attempt to achieve and maintain mount during sparring. Focus on applying learned mechanics (5 minutes).

• WHEN TO ATTEMPT:
• After successfully passing the opponent's guard and landing in side control or knee-on-belly.
• When the opponent attempts to shrimp or make space from a dominant top position.
• When the opponent exposes their back or hips during a scramble or sweep attempt.
• PRIMARY COUNTERS:
• Opponent bridges (hip escape): If the opponent bridges, immediately drive your hips down and forward, widening your base and driving knees into their hips. Maintain your high hooks.
• Opponent turns into you (underhook attempt): If they turn, transition your weight to their chest, maintain a tight grapevine, and either secure a body triangle or transition to a submission like an armbar or collar choke.
• Opponent creates frames (forearms inside knees): If they frame, immediately drive your shins across their thighs (grapevine) and use your feet to push their hips away while driving your chest down.
