Oh my. I have been doing PUB for a few weeks and I do NOT think that I will EVER be able to do these. I might be calling them by the wrong name, but it is the stability ball work at the end of the workout.
How in the world do you get this one done? I look at Cathe, and I think that even if I did manage to get myself up there, that I would end up flipping over. How may of you can do this, and of those who can, but couldn't at first, how long did it take to gain that kind of strength?
Maybe you have to be born with it?;-)
