# PPL: Push Day (Chest / Delts / Triceps) - Clinical Longevity Review & Consensus Audit

> **Consensus Verdict**: Progressive resistance exercise (30-60 min/week) is an essential, foundational pillar of human healthspan. It elevates skeletal muscle mass, triggers osteocytic bone mineral accretion, secretes endocrine myokines (IL-15), prevents sarcopenia/dynapenia, and reduces all-cause mortality by 17-40% (compounding to 40% when paired with aerobic exercise).

## 1. Executive Summary & Scores
