The Mechanical Model

A chamber is the transitional preparation phase between finishes. It must accomplish three things:

• Prepare structure for the next technique.
• Maintain vertical phase (no premature rise).
• Stay synchronized with step and rotation.

Efficient chamber:

Finish → single direct path → arrive aligned at next finish.

Inefficient chamber:

Finish → full reset → loop → re-chamber → arrive late.

That extra motion creates delay, tension spikes, and height errors.

The Economy Principle

The shortest structurally correct path is usually the strongest path.

Larger chambers feel powerful but often:

• Trigger premature vertical rise.
• Cause shoulder lift.
• Break rotational sequencing.
• Delay arrival timing.

Efficiency creates speed. Excess motion creates instability.

How Chamber Paths Affect the System

Height Control

Early full reset often causes the body to rise prematurely. Clean chamber paths help preserve vertical phase.

Rotational Control

If shoulders lift or flare during chamber, rotation sequencing is disrupted and stance alignment suffers.

Reaction Hand Efficiency

Over-pulling the reaction hand exaggerates chamber path and destabilizes posture.

Transitional Timing

Double-motion chambers create visible reset gaps. One clean path preserves continuity.

Where Chamber Paths Break Down

• Decorative looping: adding unnecessary circular motion.
• Double motion: reset early, then chamber again.
• Shoulder elevation: tension spikes during travel.
• Out-of-phase timing: chamber completes before the step begins.

Advanced Principle: Structural Readiness Without Disruption

A chamber must prepare the next structure without disturbing height, rotation, or timing.

The best chamber is barely noticeable — yet fully functional.

Diagnostic Questions

• Do your shoulders rise during chamber?
• Do your hands appear to move twice between techniques?
• Does your body rise before stepping?
• Does your technique arrive late compared to your stance?

If yes, chamber path inefficiency is likely involved.

• Beginner: learn correct chamber positions.
• Intermediate: eliminate double motion and loops.
• Advanced: chamber becomes compact, direct, and nearly invisible at speed.
