Eli5: How does exercise improve heart health? Reverse things like high blood pressure and clogged arteries?
In: Biology
The heart is a muscle. In the same way that working out your arm or leg muscles makes them stronger, working out your heart makes it stronger and more efficient. Exercise also increases your levels of HDL cholesterol, the “good” cholesterol that lowers heart disease risk by flushing the artery-clogging LDL or “bad” cholesterol out of your system and keeps your blood vessels wider which means lower blood pressure.
