Structural Work

Distance runners rarely fail from lack of strength. They fail when the system loses organization late in the run. The hips drop. The stride shortens. Force leaks sideways instead of backward.

Structural work exists to keep the system organized under fatigue. Not to build power. But to maintain coordination for 75–90 minutes.

Running fitness collapses when structure collapses.

When ribs stack over pelvis
Cue during running Wide ribs. Quiet chest.
Structural work should remain small enough
that it never interferes with the running.
