I had my 6 wk checkup on Monday afternoon and got cleared to workout. I took zumba yesterday and it was AMAZING! It was obviously quite challenging since I haven't moved my body like that in months but I felt so great afterwards. It made me feel so happy and somewhat normal again although my reflection on the mirrors didn't look so normal. Either way, it gave me motivation to get back to my normal 'look'!
Re: First real workout = success!
Yes, it's a latin based aerobic class. It's so much fun and an awesome workout! The commercial you've seen is probably for the Zumba fitness DVDs. I actually have them and they aren't great. I recommend going to a live class (if you have the time of course), it's a thousand times better.
