Train for 100

Train for 100

Muscle mass is the single strongest predictor of healthy aging. Here's the framework — backed by science, built from 100,000 real sessions.

Why muscle is the key to a long life

The research is unambiguous: the amount of muscle mass you carry in your 50s and 60s is one of the strongest predictors of how well — and how long — you live. More than cholesterol. More than body weight. More than almost any single biomarker.

This course takes that finding seriously. Built from over 100,000 real training sessions across every age group, it gives you a clear, evidence-based framework for building and maintaining the muscle that will keep you strong, independent, and cognitively sharp well into your later decades.

No fads. No supplements pitch. Just what the data and the science actually say — and what to do about it starting today.

  • Adults 35+ who want to take a proactive approach to healthy aging
  • Anyone who has been told they are "losing muscle" or has low muscle mass on a body scan
  • People interested in longevity science who want the practical application, not just the theory
  • Trainers and coaches working with aging adult populations
