4 week challenge

I joined a 4 week challenge today on SparkPeople. My aim is to lose 8 lbs (bringing me down to 115 lbs - my intermediate goal) in the next 4 weeks. That's about 2 lbs per week. I've been doing a good job eating, but I need to work on exercising regularly, more than just walking. So right now I'm going to do some step aerobics and get a jump on my exercise while Ellie's napping.
