Got the cardio covered, thanks.

I can't help hearing almost everything that is said in the hallway at work, and was surprised by the following dialogue:

"I mean, I live in a five-floor walk-up and I'm not that skinny!"
"Well, do you run up and down the flights?"
"No, but I run for exercise."
"Yes, so does she. And she also does Bikram yoga a few times a week."
"Ohhh. That'll do it."
"Yeah, she says she doesn't get enough cardio from the yoga, so she also runs."

As a regular practitioner of Bikram, my first thought was, What kind of Bikram is she doing? Because the Bikram I do? It definitely gets your heart pounding. Like, nonstop. Overachievers get on my nerves. Sigh.
