Twitter-cise... remember mousercise? I used to have one of those cassette tapes and my brother and I would jump around the room to it in our polyester PJ's with the footsies...
Yes, I do...LOL!! I remember my polyester jammies with the footsies too:) Wish I still had a pair! I'm still laughing at the thought of my PJ's, my grandma made them and my two sisters and I all had the same kind. We looked like such dorks!
It was a little hazy for me at first, too. I Googled "twitter video tutorial" and found a wonderful video that some kind Twitter-head put together and it really helped me a lot! I'm still trying to work out the fine points but at least now I "get it" enough to be fun.
