Two things are filthy in this post:
First is the "Filthy Fifty" workout at Willie's House of Pain from this morning.
Second is the fact that you can now read this blog more easily from your smart(?really?)phone, iPad, or other mobile wizardry. I'm mobi-friendly now. Evolved. Filthy.
See? filthy means more than un-clean. Learn something every day.
PS: Chelsea, I heard this morning that you might be considering CrossFit...do it. I'm calling you out. That's filthy.
