I've started doing the DVDs at home. I'm so thankful I didn't try these moves in public first!
It's been very fun so far. It gets you up and moving in a fun way and has actually encouraged me to just dance around the house more. Yes, seriously. When I was cleaning a couple of days ago, I had the music cranked and just danced away.
If you do try it, be patient with yourself and have fun. I know a couple of people who ended up getting frustrated that they couldn't do the moves perfectly. For me, it's more important that I'm trying and moving and having fun.
