Michelle - Missed your post! You were typing above my head.
Glad you enjoyed the yoga class and it helped reduce your back pain - awesome! I think I'll start the plank challenge Sunday too.
Re Jazzercise, I plan to only do Saturday morning classes. The weeknight Jazzercise classes I attended are held in a church auditorium with wonderful wood floors and a nice stage, but it's not an air conditioned space and it can get really hot in there during the summer. Both the Saturday and weeknight locations are about 8 miles away, and while it doesn't sound too bad in distance, it's further than I want to go 3 times/week. Yes, I still have the gym membership with bf, and that's only 2 miles away from home, so I'd like to keep trying to give that a go.
Have a good weekend!
