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.
