Contact mechanics determine how hands and feet actually generate usable force. Grip quality comes from pressure, surface area and force direction — not from strength. Micro-adjustments in wrist angle, hip position and skin compression often matter more than pulling harder.

Climbing holds work only when your force matches their geometry. Maximum friction occurs when you pull perpendicular to the surface, not downward. Technique becomes efficient when your body positions itself to create the correct vector — the one the hold “accepts.”

Climbing technique is fundamentally about controlling your center of mass. CoM position determines force efficiency, balance, stability, and whether a move must be static or dynamic. Elite climbers move their CoM first and their limbs second — the geometry creates the technique.
