Knee on Belly

The Knee on Belly is a dominant top position in Brazilian Jiu-Jitsu where the practitioner applies pressure by driving their knee into the opponent's midsection, controlling their movement, and limiting their ability to escape. It is highly effective for maintaining control, advancing position, or transitioning to submissions.


Key Elements

Positioning

  • One knee is placed firmly on the opponent’s torso, often near the solar plexus or lower ribs.
  • The opposite leg is posted out wide, creating a strong Base to maintain balance and adjust pressure.

Control Points

  • The knee and shin apply downward pressure on the opponent’s chest or abdomen.
  • The practitioner uses their hands to control grips, such as the opponent’s collar, lapel, or arms, enhancing stability.

Pressure Application

  • Leaning forward slightly increases pressure on the opponent, making it harder for them to breathe or move effectively.

Weight Distribution

  • Your weight is centered over the knee on the opponent’s torso while keeping your posted leg light and mobile for balance and transitions.

How to Maintain the Position

Knee Placement

  • Keep the knee firmly connected to the opponent’s torso, not sliding or losing contact.

Grip Fighting

  • Secure grips on the opponent’s collar or arms to prevent their escape or counterattacks.

Postured Base

  • Your posted leg should remain active, wide, and ready to adjust for balance.

Common Escapes

Shrimping Away

  • The opponent uses Hip Movement to slide out from under your knee and recover Guard.

Underhook Escape

  • They reach under your posted leg or body to create space and off-balance you.

Bridge and Roll

  • They try to bridge explosively and roll you off by shifting your weight.

Common Mistakes

Poor Weight Distribution

  • If your weight is too light on the knee, the opponent can escape easily.

Knee Placement Too High or Low

  • Placing the knee too close to the hips or shoulders reduces the control and pressure.

Overcommitting

  • Leaning too far forward or backward compromises your Base and allows sweeps.

Tip

To effectively "cook" your opponent using Knee on Belly, focus on applying relentless Pressure while maintaining mobility and balance. Combine it with grips to disrupt their ability to escape or counter.
