Finding clothes that meet my texture and feel demands and her aesthetic requirements

have plagued us for more than a decade, but not anymore, thanks to Roan.

Okay, the way I'd like to get started is actually with an apology.

You see, I'll admit and I'll tell you forthright that skeletal muscle is my favorite.

Cardiac is a distant second.

And I probably spent too many years not giving the heart its due.

And that's honestly because I came from what would be typically called as an anaerobic sport background.

You see, I was much more interested in things like football.

a little bit of basketball, baseball, and things that require not a lot of endurance, but a lot of power.

And so I didn't really necessarily appreciate.

In fact, I directly said that the heart was not nearly as important as your skeletal muscle.

I've come since to learn that that was the wrong approach.

And I'll tell you more why about even if you're into those types of activities, you should care deeply about the functionality of your heart and how that can absolutely improve your performance, even in situations and scenarios like that.

Okay, so as a quick reminder here, remember your body has three main types of muscles, smooth, cardiac, and skeletal.

Now, there's a number of structural and functional differences between these three.

And just very quickly, smooth muscle lacks contractile properties.

And so some of the things we're going to get into later, the microanatomy of smooth muscle, it doesn't have.

And so it lacks the ability, again, to contract.
