The morning after Day 2...

Last night after the day 2 workout I felt fine, no pain - no nothing.  But this morning I woke up sore all over.  It's like I had worked out every part of my body with weight training, incredible.  From my calves to my shoulders and biceps. I truly didnt expect to wake up like this.  This just means that it's working and that I am doing something right.  I am afraid of todays workout since I'm so sore that I wonder if I'll make it past the warm up.
