Long-form reference for lifters and runners.

Pillar guides go deep on the literature — Schoenfeld, Seiler, Morton, Kouri, Riegel. Standard guides answer a single question, with every specific number traceable to a source. No plans, no protocols, no “transform” language. Just what the evidence supports, with dated caveats.
