Training Strong
The most accessible longevity lever. Dose-response all-cause mortality: 7,000 vs 2,000 steps/day ~47% lower death, benefit detectable from ~2,600. Observational but large, consistent, and biologically coherent. Empower-first anchor #1. Cost

Evidence strength
How confidently the research supports a claim. Strength describes the evidence, not our endorsement.
StrongLarge or repeated randomized trials point the same way (a firm "no effect" counts too).
ModerateGood trial evidence, but fewer, smaller, or less consistent studies.
EmergingEarly trials or pooled signals, real but not yet settled.
PreliminaryMostly indirect, animal, or observational evidence.
