My Least Favorite Exercise

Sure, there are a LOT of exercises that I hate, but the one that is the MOST hard for me to do:

The Plank

I mean, I've been doing the ab workout for quite a while and I still can't hold this position on my feet for very long without shaking and my back hurting.  I kind of think that means I need to work on it more.  I wonder if my personal lack of muscles in that area could be a source of my tailbone problems?

Who knows, but I know if I hate it, I need to keep working on it.  Thanks to Lindsay, and Jenny I'm sure I will.
