You're listening to Bulletproof Radio with Dave Asprey.

Today's episode is a special edition of Bulletproof Radio.

A good friend and mentor Charles Pollackwin, a man who has helped elite professional athletes and Olympians win hundreds of medals.

Who's been on the show just passed away unexpectedly.

And to honor his passing, I'd like to share episode 378 of Bulletproof Radio again in this special edition.

Charles was one of the most knowledgeable biohackers I've ever met a guy who I could call if there was something that I didn't know and he'd probably know it whether it was a bizarre Russian peptide or an unusual way to tell whether fat deposition in the belly was caused by hormones or something else.

He was a wealth of knowledge and was always eager and willing to share it.

And I had the great pleasure of supporting Charles on growing his own business and was just incredibly sad to hear of his passing.

And we lost an amazing biohacker when he passed.

So I wanted to share his amazing knowledge one more time in this episode.

We talk about what happens to your brain when you put muscle on versus what happens when you do cardio and a bunch of other things that also share his amazing sense of humor.

I know that you will enjoy this episode.

I enjoyed recording it and I missed Charles.

Today's cool fact of the day is about the largest muscle in your body.

If you don't know what it is, it's actually your gluteus maximus as they say, baby got back.

But what's the smallest muscle?

This is when you probably haven't really thought about.

So listen carefully.

It's called the stupidius muscle.

And of course it's in your inner ear, which is why you're listening carefully.

It's about 500ths of an inch.

And it stabilizes the smallest bone in your body called the stopes or stopes.
