On July 24, 2025, the American pro wrestling celebrity Hulk Hogan, whose real name was Terry Bollea, died at the age of 71. Hogan had chronic lymphocytic leukemia and a history of atrial fibrillation, or A-fib, a condition in which the upper chambers of the heart, or atria, beat irregularly and often rapidly. His cause of death has been confirmed as acute myocardial infarction, commonly known as a heart attack.
Hogan became a household name in the 1980s and has long been known for maintaining fitness and a highly active lifestyle, despite having had 25 surgeries in 10 years, including a neck surgery in May.
Hogan’s death has brought renewed attention to the importance of maintaining heart health through exercise. Many people think that bodybuilders are the “picture” of health. However, the truth is that too much muscle can increase strain on the heart and may actually be harmful. It may seem ironic, then, that people who exercise to extreme levels and appear healthy on the outside can, in fact, be quite unhealthy on the inside.
As the director of sports cardiology at the University of Colorado Anschutz Medical Campus, I see patients of all age groups and at varying levels of fitness who are interested in promoting health by incorporating exercise into their lifestyle, or by optimizing their current exercise program.
