Functional Performance Report

More Than Just a Six-Pack.

The core is not a shield; it is a pressurized cylinder. Its true purpose is not to create motion (crunches), but to resist motion (stability) and transfer energy from hips to hands.

The 3 Myths of Core Training

  • !

    Myth: "Crunches burn belly fat."
    Reality: Spot reduction is impossible. Crunches flex the spine under load.

  • !

    Myth: "Suck it in."
    Reality: Stability comes from pushing out (bracing) to create pressure, not hollowing.

  • ✓

    Truth: "Anti-Movement."
    A strong core prevents the spine from buckling under heavy loads.

The 3D Cylinder

Forget surface-level aesthetics. Real strength lies in the deep layers that create the "corset" effect.

The "Six-Pack" Shield

Physics of the Core

Why do we plank instead of crunch? The data on spinal compression tells the story. Stability protects; flexion degrades.

Spinal Compression Loads

Newtons of Force

Force exerted on the L4-L5 disc during common exercises. 3300N is the NIOSH danger limit.

The "Energy Leak"

Power Transmission

Percentage of power transferred from legs to arms. A weak core leaks energy like a flat tire.

Stability Protocols

Select a focus: Resist motion (Anti-Move) or Integrated power (Dynamic).

Daily Core Hygiene

A strong core isn't built in one session. It's built by activating the "Cylinder" daily before you lift or run.
