I LOVE Zumba! It is too much fun and makes me feel great. I can't afford a monthly gym membership but the videos that are available are just as fun.
@Alaskagirl if you are nervous about it, I would recommend picking up a starter video. You can find youtube tutorials as well. I have one that is 25 minutes and one that is a full hour when combined with some yoga warm ups. Both videos have separate sections that walk you through the moves slowly, so you can learn them step by step. I found it very useful to go through those a few times. I would feel confident walking into any class at this point, even if they use some different moves I feel like I have a grasp of the basics.
I wanted to join our Y- again not in our budget. They said when we toured back in October that they offer Zumba in the basketball courts and you have to come early to get a ticket to save your place. I had been doing it at home all summer and was not at all surprised it was so popular. Doing it with a large group like that would be even more fun!
