In our last installment of Is It Porn?, 72% of you agreed that boob punching is NOT porn. We're glad that's settled, but we've come across a whole new confusing genre of possible porn -- workout videos on YouTube.

Denise Austin is a 51-year-old former gymnast with her own fitness empire, which includes books, television shows and yes, workout videos. But when we innocently typed the exercise expert's name into YouTube, we found a bounty of saucy clips with titles like "Denise Austin- Inner Thigh, Ass and Crotch Shot- Wow!!" and "Denise Austin spreads em WIDE." Most of the clips are under a minute long, seemingly too short for the watcher to break a sweat, unless the videos have some other, unintended purpose.
