Beat me to it, I was about to comment just that. I've been going to the gym for about 5 years now and been assisted by trainers and I'm still lost on what she was trying to achieve or why she was getting so winded in the process. It seems like a stretching exercise but I have no idea how it could get tired so quickly.  Then again, I'm no expert either. I'm confused, but fat's stupidity has no limits, so I wouldn't be surprised if it had no clue what it was doing either. I still would like to know if this has any basis whatsoever on an actual form of exercising
