Focus: How exercise dose and intensity shape heart structure and aerobic fitness across the lifespan
Dr. Benjamin Levine is a sports cardiologist who founded and leads the Institute for Exercise and Environmental Medicine in Dallas, and advises major sports leagues and NASA. Emphasizes how inactivity, training dose and intensity reshape the heart itself, using bed rest, spaceflight and lifelong-athlete studies as natural experiments. Draws primarily from his own physiology trials and large cohort data such as the Cooper Clinic, and is careful to separate small mechanistic studies from outcome evidence.
