INSIGHT

Helical Structure Underpins Human Movement

  • Human bodies use a helical, spring-like structure that stores and releases energy efficiently.
  • Recognizing this shape explains movement, resilience, and why curves are triangulated not purely curved.
INSIGHT

Structure Predicts Tendencies, Not Fate

  • Body shape biases create probabilistic tendencies for force vs. velocity performance.
  • Use structure as a proxy to predict likely strengths and limitations, not absolute destiny.

Force–Velocity Trade-Off By Archetype

  • Wider helical builds skew toward high force but lower velocity; narrow builds favor velocity over force.
  • The force–velocity trade-off explains why different athletes excel with different training emphases.
