Modified Mount BJJ: White Belt Guide
☰目次
Learn the Modified Mount in BJJ. This precise guide for white belts focuses on biomechanics, safety, and effective technique for control.
White
Modified Mount is a dominant control position achieved from standard mount, isolating an opponent's upper body for submission or transition.
White belts often struggle due to a lack of understanding of weight distribution and framing, leading to loss of control and potential injury.
The key insight is leveraging your hips and base to create a tight, inescapable connection, preventing the opponent from bridging or shrimping effectively.
グリップ・生体力学
- From standard mount, secure both of the opponent's wrists with a gable grip (fingers interlocked).
- Shift your weight forward, driving your hips down and slightly towards your opponent's head, creating a forward lean.
- Simultaneously, bring your knees wider, almost parallel to the mat, to widen your base and prevent them from shrimping out.
- Maintain constant downward pressure through your hips and chest, keeping your back straight.
- Your elbows should be tucked in, creating a tight frame against your opponent's upper body.
- Ensure your hips are lower than your opponent's hips, preventing them from lifting you.
- Your gaze should be forward, maintaining situational awareness and preventing your head from being attacked.
⚠️ 白帯の注意点
- Incorrectly extending your knees outwards without hip pressure: Can lead to hyperextension of the knee ligaments (MCL/LCL) if the opponent bridges powerfully.
- Lifting your hips too high off the opponent's body: Creates a space for them to shrimp or bridge, potentially causing your own knee or ankle to twist when you fall.
- Grabbing the opponent's sleeves or arms loosely instead of a gable grip on wrists: Allows the opponent to easily pull their arms out, compromising your control and opening them to escape.
ドリル段階
- Solo drill: Practice moving from standard mount to Modified Mount with no opponent, focusing on hip and knee angles. (10 reps)
- Partner drill (no resistance): Partner lies flat on their back. Execute Modified Mount transition. (10 reps)
- Partner drill (light pressure): Partner offers minimal resistance to being mounted and controlled. Focus on maintaining position. (5 reps per side, 50% resistance)
- Transition drill: Start from side control, achieve mount, then transition to Modified Mount. (5 reps per side, 50% resistance)
- Submission entry drill: From Modified Mount, practice the initial setup for a common submission like an armbar, without completing it. (5 reps per side, 75% resistance)
- Live rolling: Focus on achieving and maintaining Modified Mount for at least 10 seconds during rolling. (Start with 3-5 minutes, 90% resistance)
使うタイミング・カウンター
- WHEN TO ATTEMPT:
- When you have successfully established standard mount and the opponent is attempting to bridge or shrimp.
- When you have isolated one of the opponent's arms and are looking to transition to an armbar or other submission.
- When the opponent is turtled and you are looking to transition from mount to a more dominant control.
- PRIMARY COUNTERS:
- Opponent bridges powerfully: Shift weight to your toes, keeping hips low. If they lift you, immediately attempt to fall to the side and re-establish guard or side control.
- Opponent shrimps effectively: Widen your base further and drive your chest into their chest, preventing them from creating space.
- Opponent grabs your leg to sweep: Maintain your base by keeping your knees wide and your hips heavy. Use your free hand to break their grip.

よくある質問・トラブル
This often happens because you are rounding your back and not engaging your core. To fix this, focus on keeping your spine neutral and using your glutes and hamstrings to drive your hips down. Think of it like a controlled plank with added hip pressure, not just leaning forward.
Against a larger opponent, your weight distribution is paramount. Ensure your hips are significantly lower than theirs, creating a downward force. Use your forearms and elbows to create tight frames on their chest and shoulders, preventing them from shrugging or bridging effectively. Your base needs to be wide.
Modified Mount is a transitional and attacking position. While it provides excellent control, its primary purpose is to set up submissions like armbars, kimuras, or even transitions to other dominant positions. You should always be looking for opportunities to advance your attack or position.
