I've been doing this for a little over two months now (minus my 10 days away in San Diego) and still really liking it. It's become part of my routine. This morning when I woke up to go to class it was JUST starting to grow light outside though, so I think the winter classes will be more difficult. Especially once I have to throw on layers just to go outside. But I love going to class and I definitely think I'm in the best shape I've been since I was 16 and running cross country. Granted, that's not saying a lot...but I'm still proud of myself for going to this consistently.
The schedule I've set up for myself since returning from San Diego is 2 days of classes followed by one day of rest. Some weeks this ends up being 4 classes a week and others 5. I think that's a reasonable balance. My progress since my last update has not been dramatic, but it's noticeable to me. All the improvements are small and gradual. I'm still on the 1 and 2 pound weights, but they are getting a little easier. My flexibility is improving and I can put my leg on the bar easier. I'm not shaking as much during the thigh exercises so I think I need to start going a little lower. All in all, slow but steady!
