Trying Zumba is probably the best decision I've ever made. Actually... the best decision my DAD ever made for me lol
My dad is the Executive Director of our local YMCA. He likes to get me to try out new classes so I can let him know what I think. A while ago, when I had mentioned to him that I was going to get back in shape after baby, I asked him if I could teach a hip hop class in the future. A week later he told me Zumba would be starting up and that it's like the video I sent him. I read a bit on it and told him that is NOT hip hop (and nothing like the video I sent lol my dad is so cute) but once I youtubed it (search Zumba on youtube, click the first video, amazing!) it DID look fun!!
I tell you what... I've NEVER in my life worked up a sweat like I do in Zumba. It's a 60 minute class and you do not stop moving the whole time. The very first day I felt like I was going to throw up. The next morning my body hurt like it was in pieces. (It does get easier!)
The nice part about Zumba is that you don't NEED to be good at it. You can do your own thing (my friend Amanda & I like to goof off and battle each other with moves lol) step wise. The most important thing is to keep moving and have fun. I do have a heavy dance background, which I think hinders me more than helps. I'm used to counts and the "right way" to do things. With Zumba you get neither. The instructor starts, you follow. You technically can't even call him or her an instructor, because you're just following what they do.
Zumba is one of the hottest exercise crazes in the WORLD. Check out your local facility and see if classes are offered. If classes aren't offered you can request them. This is something that you should definately check out.
