Well, the good news that I haven't died yet. The gym is doing its best, but I'm still here. Mwahaha!
The bad news is that I hurt like you wouldn't believe. Holy carp, I really pissed off some muscle groups with my three months of sloth and they are getting their payback now.
Of course, it's not as bad as it was yesterday. Yesterday, just thinking hurt. And I managed to drag myself back to the gym this morning and do it all again (I think some of the machines actually laughed at me, but it was noisy because of the step aerobics class, so I can't be sure.) I've got to be nuts. Really.
