Dripping in Sweat

I consider myself to be a fairly un-sweaty person. I can usually do a whole workout, pushing myself pretty hard, and barely break a sweat. Today I did level 2 of Jillian Michaels' 30 Day Shred and I am SWEATING. Workouts didn't exactly happen over the weekend for me, so it's not a surprise that it was a fairly hard workout for me, but man, I'm really sweaty, and I feel GREAT.
