Ouch!

Ok, I was brave and tried something new today...spin class...and all I can say is ouch! And not in a good workout kind of way...more like a "I just gave birth and can't sit down" kind of way. The instructor said it would take two weeks for our rear ends to get used to it, but I'm not sure I'll be able to sit or stand tomorrow to find out if I can even try it again Friday. On the other hand, it burns 500 calories in 45 minutes! I really hope I've lost something when I weigh in for the Holiday Trimmings thing on Wednesday.
