How does Jennifer Aniston do this daily?

Oh my God,  y'all.  I attempted yoga today.....it wasn't pretty.  Of course the instructor was a tall, skinny blonde that's double jointed.  I, of course, was totally unprepared for what was in store.  Luckily, one of my old Allstate work buddies is on vacay, and was taking the class as well- she provided encouragement.  At one point I looked at her, said "this shit is hard," and burst out laughing.  Because I'm a glutton for punishment, I think I'm going back next week.  I can't let the Downward-Facing Dog intimidate me.  Must also remember to wear a thong or seamless underwear next time as panty lines are not attractive in yoga pants; especially when your a$$ is in another person's face the.whole.time.  SMH......
