Discover the Art of Seamless Transitions: Bill Cooper's Mount to Kneebar Mastery
In the world of Brazilian Jiu-Jitsu (BJJ) and mixed martial arts (MMA), chaining attacks from dominant positions like the mount can turn a good grappler into a nightmare for opponents. Bill 'The Grill' Cooper, a seasoned BJJ black belt known for his aggressive and creative style, showcases a jaw-dropping sequence that starts from a high mount and flows effortlessly into a kneebar submission. This isn't just a one-trick pony move—it's a full attack chain that keeps pressure on while setting traps for counters.
Whether you're rolling in the gym, prepping for a BJJ tournament, or integrating grappling into your MMA game, mastering this sequence can elevate your top game. We'll break it down step by step, add some pro tips, and discuss how your gear plays a role in executing it smoothly. Let's get into it.
Why This Sequence Works in BJJ, MMA, Wrestling, and Beyond
Mount is one of the most dominant positions in grappling sports. From here, you threaten armbars, triangles, and chokes, forcing your opponent to defend desperately. Bill Cooper exploits this by faking one attack to bait a reaction, then capitalizing with a leg lock. Knee bars are high-percentage finishes, especially in no-gi scenarios common in MMA and submission grappling.
This chain is versatile:
- BJJ Gi: Use collar grips to control posture.
- No-Gi/MMA: Rely on underhooks and wrist control with rash guards and fight shorts for better grips.
- Wrestling Integration: The mount pressure translates to ride-time control before the leg attack.
Pro tip: Always drill this with a partner at 50% speed first to groove the timing. Gear up with quality compression shorts from Apollo MMA to avoid wardrobe malfunctions during explosive transitions.
Step-by-Step Breakdown: From High Mount to Kneebar Lock
Step 1: Establish the High Mount and Break Posture
Start in a technical high mount, knees high on your opponent's torso for maximum control. Your hands swim inside their arms to secure wrist control or isolate one elbow. Drive your chest into their face to flatten them out—think heavy top pressure like in wrestling rides.- Key Detail: If they bridge, post one hand on the mat and base out with your hips low momentarily.
- Common Mistake: Staying too upright; drop your weight to smother escapes.
Step 2: Switch to S-Mount for Armbar Threat
Transition smoothly to S-mount by sliding one knee up high behind their shoulder while trapping their far arm with your elbow and knee. Your free hand grips their isolated wrist or bicep.- Grip Fighting: In gi, sleeve grip their far arm; no-gi, use a two-on-one wrist ride.
- Pressure Tip: Rotate your hips slightly to off-balance them, making the armbar setup look imminent.
Step 3: Fake the Armbar to Bait the Defense
Go for the classic armbar setup: swing your S-mount leg over their head, isolating the arm fully. But instead of finishing, release pressure just enough to bait them into tucking the elbow or turning away.- Timing Hack: As they defend (pulling the arm or bridging toward you), that's your cue.
- Why It Works: Defenders expect the armbar, so the fake creates openings elsewhere.
Step 4: Explode into the Kneebar Entry
With their defense committed, abandon the arm and attack the near leg. Step your outside foot to the mat, trapping their ankle with your armpit while your other hand cups behind their knee. Rotate away, pulling the leg across your body for the figure-four kneebar grip.- Technical Specs: Extend the leg fully while lifting your hips—aim for 90 degrees of hip elevation.
- No-Gi Adjustment: Use spandex shorts or board shorts for slick control without fabric snags.
Step 5: Secure the Finish and Manage Resistance
Once in the kneebar, arch your back and squeeze your elbows together while pushing down on the toes. If they roll to escape, follow with your hips to maintain the angle.- Finishing Torque: Rotate your hips away from their body for maximum hyperextension.
- Safety Note: Tap early in training—knee ligaments don't forgive.
Drilling Tips and Variations for All Levels
To make this yours:
- Beginners: Focus on positions 1-3 without the kneebar. Build comfort in S-mount.
- Intermediate: Add speed drills, 5 reps per side.
- Advanced: Chain to back take if they fully turn away, or triangle from the fake armbar.
Gear Recommendations for Optimal Training:
- Rash guards prevent mat burns during rotations.
- Grappling shorts with grippy lining for leg control.
- Mouthguards and lightweight gloves if blending with MMA sparring.
