It is not connected to bone.

That's not the point.

We're not trying to cause movement.

It is really just connected to itself.

So because of that, we can't ask it to go over any additional range of motion.

So that factor gets thrown out.

The only thing we can possibly do is...

is put more blood back into the heart, which puts it on an eccentric stretch.

That's our only mode here.

Now, eccentric exercise does lead to excessive soreness if done especially heavy or in a novel fashion with traditional exercise.

And so eccentric exercise is something to pay attention to, but the fact is we don't have the ability to overload the heart more than the maximum amount of blood we already have in our system.

So there's no novelty we can add to it that it's not already used to.

By the way, to answer your question, what's the only muscle not directly attached to the bone?

I'll give you a hint.

You can see it on me right now.

And if you were my five-year-old, you would love to show it to me all the time.

It's your tongue.

Pretty cool, right?

All right, going back to business here.

So it's not range of motion.
