In this Huberman Lab Essentials episode, I revisit episode 2 of my six-part guest series with Dr. Andy Galpin, PhD, an exercise scientist and expert in human performance. We discuss how strength and muscle growth (hypertrophy) differ and why resistance training is important for maintaining physical function as we age. We also explain how to build effective training programs using progressive overload, exercise selection, repetition speed and weekly training volume. Dr. Galpin shares practical tools for developing strength, power and muscle size, including how to adapt workouts to your goals, equipment and schedule.
