What are Levers?
Levers use a body segment rotating around a support point to transfer force, with the contact position and angle determining the mechanical advantage.
When a movement feels heavy, check where the support point sits and where you apply force. A small hip or grip adjustment can change the effort needed.

Building Blocks
- Identify the support point and the body segment that will move around it.
- Adjust contact distance and angle before adding effort.
- Keep a firm connection between your body and the lever.
- Reposition when the opponent moves the support point or changes the angle.
Prerequisites
Fulcrum Identification and Creation: The ability to recognize existing fulcrum points in positions and create new fulcrums through body positioning. This includes understanding how hips, shoulders, knees, and contact points serve as pivot points for rotational force application. Practitioners must develop sensitivity to identify where maximum mechanical advantage exists in any given position.
Lever Arm Ratio Calculation: Intuitive understanding of how to maximize the distance from fulcrum to effort point while minimizing distance from fulcrum to resistance point. This skill involves constantly adjusting body positioning to create favorable mechanical advantage ratios, typically seeking 2:1 or greater lever arm advantages whenever possible.
Force Vector Optimization: The capacity to apply force in directions that maximize rotational effectiveness around identified fulcrums. This requires understanding perpendicular force application and recognizing when force vectors are misaligned with optimal leverage angles. Practitioners learn to adjust angles to ensure force travels the most efficient path.
Compound Leverage System Building: Advanced skill of combining multiple simple leverage systems to create exponential mechanical advantage. This includes using primary leverage to establish position, then adding secondary and tertiary leverage systems that build upon the initial advantage. Common in complex positions like truck or advanced back control variations.
Structural Integrity Maintenance: The ability to maintain rigid connections throughout the kinetic chain from effort source through fulcrum to resistance point. Any weakness or collapse in this chain dissipates leverage effectiveness. This skill involves core engagement, proper alignment, and eliminating slack in the leverage system.
Dynamic Leverage Adjustment: Real-time modification of leverage systems as opponent responds and positions change. This includes recognizing when leverage systems collapse, identifying new fulcrum opportunities, and seamlessly transitioning between different mechanical advantage setups without losing control or position.
Opponent Leverage Disruption: Understanding how to identify and break opponent’s leverage systems while establishing your own. This includes recognizing their fulcrum points, extending their lever arms unfavorably, and positioning yourself where they cannot generate mechanical advantage. Essential for both offensive and defensive applications.
Body Center of Gravity for Leverage: Strategic use of body weight positioning to serve as effort force in leverage systems rather than relying on muscular strength. This includes understanding how gravity, momentum, and weight distribution can be directed through optimal leverage angles to create technique effectiveness with minimal energy expenditure.
Where to Apply
Butterfly Guard: Bring your hips into position under the opponent so a hook can lift the thigh while upper-body grips direct the sweep.
Closed Guard: Use legs and hip angle with your grips to move the opponent’s upper body instead of pulling with the arms alone.
Spider Guard: A sleeve grip and foot on the biceps act on the arm from different contact points to control distance and balance.
Standing Position: Place your body and grips so a takedown entry creates a support point around which the opponent can be redirected.
How to Apply
- Assess current position and identify available body contact points: Survey all points where your body contacts opponent or mat. Recognize which contact points can serve as potential fulcrums versus which can extend as lever arms. Consider how current body positioning creates or prevents leverage opportunities.
- Identify or create primary fulcrum point for intended technique: Position body segment (hip, shoulder, knee, hand) to serve as stable pivot point. Ensure fulcrum placement creates favorable geometry for intended movement direction. Verify fulcrum stability through structural alignment and base.
- Evaluate lever arm ratios on both sides of fulcrum: Measure distance from fulcrum to effort application point versus fulcrum to resistance point. Adjust positioning to maximize effort lever arm length while minimizing resistance lever arm length. Seek minimum 2:1 advantage when possible.
- Optimize force vector angle relative to lever arm: Position body to apply force perpendicular to lever arm for maximum rotational effectiveness. Recognize when force angle is suboptimal and adjust body positioning. Understand that even small angle deviations significantly reduce leverage effectiveness.
- Establish structural integrity throughout kinetic chain: Engage core and align body segments to create rigid connection from effort source through fulcrum to resistance point. Eliminate slack or weak points that dissipate force. Verify that force transmission pathway remains solid during movement.
- Identify opportunities for compound leverage systems: Look for secondary and tertiary fulcrum points that can be added to primary leverage system. Consider how multiple simple levers can combine for exponential mechanical advantage. Balance complexity against execution reliability.
- Monitor opponent’s counter-leverage attempts: Recognize when opponent creates their own fulcrum points or attempts to break your leverage systems. Adjust to maintain favorable lever arm ratios or transition to new leverage opportunities before current system collapses.
- Reassess and adjust leverage dynamically during movement: Continuously evaluate leverage effectiveness as position changes. Be prepared to abandon compromised leverage systems and establish new ones. Develop flow between different mechanical advantage setups rather than forcing failing leverage applications.
