Spin class today

I took my first spin class since I got pregnant with Lila and it felt good! My bodybugg said I burned 200 calories in the 30 minute class, which I thought was on the low side. It supposedly doesn't measure cycling well. I want to wear my heart rate monitor next time. I have about 300 calories left for a snack before bed. Yesterday I was at 1200 calories, and did 1 hour of weights with the trainer. The hour went by so fast! I only had time to do 15 min on the elliptical before I had to get the kids home for dinner. I heard Lila shrieking from the daycare! I really want to be by 152 by Friday and would love to be at 150 by next Friday.
