I'm sore. but that's a good thing...

...it means I worked hard right? I went back today for Step and Core and the boys had a great time at the babysitting. They had a lot of kids so they moved half up to the racquetball court and when I went to get them about half the kids were doing laps around the track. One of mine was leading the pack and the other was bringing up the rear. Gibson was so proud of himself to be doing "extherthise". I was a bit sore this morning but I pushed through it. I like doing the classes because I can't just quit in the middle like I can do at home with a tape. Too embarrassing! I also like that I feel sore because it tells me I am working different muscles. I am never sore after the Treadmill, even if I go for an hour and a half. My leg muscles are used to that motion. I am planning next week and I will try to go 3X.
