Losing Weight!

For several years now I've struggled with my weight. Not so much the number, I try not to fixate on that, but how I feel and how my clothes fit. It's been a big adjustment because growing up I never had to worry about it. But gradually I was having to buy bigger sizes and I liked pictures of myself less and less. But it's hard to stay motivated and work out when I'm not used to having to. After the failed IVF attempt I got into a good groove and felt really good. I never weighed myself, but I was fitting comfortably into all my clothes and getting compliments, so that's all that matters! Then I got pregnant and had no energy. I was lucky, I only gained 29 pounds the whole pregnancy and all but two of them were gone by my 6 week post baby checkup. I felt really good for awhile after that. But then I settled back into old bad habits and it got colder and we couldn't walk outside as much. I never weighed myself, but I started feeling frumpy and uncomfortable in my clothes and in pictures. 
A couple of days ago a friend at church suggested we do a holiday weight loss challenge - we all pitch in $20 and set a 6 week timeline to lose weight. I'm not sure how many people signed up, and it's not usually my kind of thing, but I did. It got really "official" when one of the women from church offered to do all of our weigh ins at her nutrition club. So today I went and got weighed and measured. I didn't know what to expect from my weight, but I was still at my pre-baby weight. I'm not sure realistically what I should aim to lose, so I'm just going to enjoy working out and hopefully feel better in my clothes and in pictures.
I've been pinning workout ideas on pinterest for awhile, so now I get to actually use them! Since the most I've done in 8 months is push a stroller around the neighborhood, I'm going to start off slow and gradually add things. So I'm starting with a slightly modified version of this:
