Episode Description
After 40, your body changes. Muscle loss accelerates. Recovery takes longer. Injuries don't heal like they used to.
Most people over 40 fall into one of two traps: Either they ignore the biological reality and grind themselves into injury, or they assume they're broken down and settle for watered-down "everything workouts."
Both approaches fail.
In this episode, you'll learn the science-backed approach to building muscle after 40—what actually works for maintaining strength, minimizing injury, and training for longevity.
Here's what we cover:
- The biological truth about training after 40: sarcopenia, recovery decline, and why exercise selection becomes critical
- The 6 movement patterns you need every week for balanced, bulletproof training
- Why isolation exercises matter MORE as you age (and how to use them intelligently)
- The shift from heavy weight to moderate rep ranges—and how to measure progress without chasing 1RM PRs
- Which exercises to avoid (ballistic movements, risky shoulder positions, heavy barbell lifts that stress aging joints)
- The 4 biggest training mistakes derailing your progress
- Rapid-fire nutrition and supplement recommendations: protein targets, creatine, fish oil, and alcohol limits
Whether you're entering your 40s or deep into middle age and wondering if you're doing it right—this episode cuts through the noise and shows you what works.
