I would think because your heart beats faster, but probably not with more intensity like the other muscle groups that go under heavier than typical loads. Plus your heart never stops so I guess DOMS never even has a chance! Lol!

One: it’s a different type of muscle. Two: it gets a steady supply of nutrients to repair and replenish itself.

Iirc, The reason your muscles hurt is because of micro tears from the strain of a work out that cause a build up of lactic acid. This acid is what makes you sore.

The heart doesn’t tear like your other muscles do. And there’s not as many pain receptor around your heart as there are around the surface of your body.

For example, if someone feels a wierd pain shoot down your left arm (I think thats right), it could mean you’re having a heart attack (referred pain). This is because there’s not enough pain receptors by the heart for it to tell you hurts, so it sends the signal elsewhere. That’s also why you don’t “feel” most of your visceral organs, just their effects on the body. Like the thumping of your heart.

It’s been a while though, so please correct anything I got wrong.

Edit: fixed point about referred pain

Your muscles build up lactic acid when they don’t get enough oxygen. Your heart is a different type of muscle so it don’t produce lactic acid.

How would our hearts ache ? We can’t really feel them.

No pain receptors, no pain.

The reason your muscles are sore are bc of micro ruptures that you make when exercising. The heart doesn’t suffer those ruptures and therefore , it can’t be sore.

You are “semi” injuring your muscles. Like a scar, it heals back a little “extra”, bigger, etc.

For your heart, you aren’t injuring it.

Your lungs are likely to feel it more than your heart. It pumps everyday, sometimes more if you drink caffeine
