Dr. Andy Galpin: Does Cardio Ruin Muscle Growth?.

#zone2cardio #andygalpin #andrewhuberman #musclebuilding #cardioforthenerd #workoutscience In this expert conversation, Dr. Andy Galpin and Dr. Andrew Huberman clear up the common myths surrounding the "interference effect" between cardio and muscle building. Learn why Zone 2 cardio done at a conversational pace won’t compromise your hypertrophy or strength gains, and how exercise selection—specifically choosing concentric-based movements like cycling, rowing, or sled pushes over high-eccentric landing exercises like running—can prevent extreme muscle soreness and joint pain. Dr. Galpin breaks down the history of concurrent training research, explaining how energy balance and exercise modality dictate whether cardio inhibits muscle growth. Additionally, discover a simple weekly endurance framework: hitting your near-maximum heart rate once a week with high-intensity interval protocols (such as 30 to 90-second sprints or burpees) to optimize stroke volume, vascular health, and overall physiological fitness without burning out.
