At first it appears to be just another YouTube workout video starring a well-toned, scantily clad female. She wants to convince viewers that they, too, can look like her with a few basic exercises, done in the comfort of their own homes.

In the funny business of creating a fitness enterprise in an online world, Charlie James has had some success. She even has her own YouTube channel.

But sometimes when you do something in your home, everyone gets a little too comfortable.

In one of her videos, "Burnout Challenge - HiitLean #11," the sexy James is doing a Squat Front Raise. Guys, you'll be impressed.

But watch what happens at 22 seconds into the video. Look to the left of the screen.

There is a man sitting on a toilet doing what men on toilets do.

The camera keeps rolling as if it's all perfectly normal. By the time James moves on to the next exercise, the bathroom door has, thankfully, been closed.

"She's not the only one squatting," tweeted @TraderRLH in reaction.

Indeed.

I've been in television a long time, and there are a few basic rules. One of them is to pay attention to what's going on. I know, details. Then again, the toilet "mistake" may have been on purpose. James' videos usually get 20,000 to 30,000 hits. Burnout Challenge has nearly 1.2 million hits as of this writing. You could say she's flush.
