Oh, I was sweating like a pig, just ask Kristin.
Even when I was in shape, playing full court basketball for 3 hours straight.... I would still throw up. Granted, it was just water, it told me I was pushing a little hard.
BTW, met up with Clarkey last night and he told me about www.myfitnesspal.com. They have everything you can think of in the way of food, so you can log everything you eat, and your calories burned during a work out. They also have phone apps, so you don't have to jump on a computer to log everything. You can even scan the bar code of the thing you're eating and log it that way too.
