Cardio exercises are great for you, but I’m confused. Since the heart is a muscle, does exercising it make it grow bigger, which could lead to heart disease?
My father has a enlarged heart and this question crossed my mind.
In: Biology
There’s a difference between an enlarged heart caused by heart disease (dilated cardiomyopathy) and a well trained athletic heart. A dilated heart is weaker and less able to pump blood. It’s possible to do so much athletic training that changes happen in the heart but these are generally not harmful.
