Even if you get more clogs in your arteries from super intense training, you’re still less likely to die from heart problems than someone who doesn’t exercise at all.
Scientific Claim
High-volume, high-intensity endurance exercise increases coronary artery plaque burden without increasing all-cause or cardiovascular mortality risk in otherwise healthy individuals.
Original Statement
“High levels of intense exercise increase plaque volume, but the additional plaque doesn't seem to correlate with increased risks of death from heart attacks or other causes for these people who exercise.”

Sex Differences in the Impact of Exercise Volume on Subclinical Coronary Atherosclerosis
The study found that men who exercise a lot (like elite athletes) have more calcium buildup in their heart arteries than regular guys, but it didn’t check if they died more or less — so it supports the idea that intense exercise can increase plaque without proving it’s dangerous.
People who exercise a lot (like marathon runners) tend to have more plaque in their heart arteries, but they don’t die more often than people who exercise less — in fact, they live longer. So the study supports the idea that more exercise = more plaque but no extra risk of dying.
People who exercise a lot (like marathon runners) tend to have more plaque in their heart arteries, but they don’t have more heart attacks or die more often — in fact, they live longer. So the study supports the idea that this kind of exercise is safe even with more plaque.
Potential mechanisms linking high-volume exercise with coronary artery calcification
This study found that super-active older men who run or bike a lot tend to have more calcium buildup in their heart arteries, but they don’t die more often from heart problems — which matches the claim that intense exercise can increase plaque without raising death risk.
