Man I've been working out with Zumba again this whole week. Its been about almost a year since I've done it I was at Expert Level with Medium difficulty which I though was good Id almost dance everyday sometimes twice a day but i did workout a lot with my Elliptical Trainer. I must say it does do a whole body workout and makes you sweat like crazy I'm getting back into it and I'm at Intermediate Level with Medium Difficulty which isn't bad for almost a year hiatus really. I always like to mix things up I never like doing the same routine over and over cause after awhile your body gets use to it and you don't see the results anymore or the results your wanting. I still use my Elliptical Trainer with Nordictrack and I also life weights and more. I feel its good to have my body engaging in something different to keep it on its toes so it doesn't get use to just one thing.
