I just started the INSANITY 60 day challange......and if you want to sweat..... this is the workout for you! I am on my first week and already noticed changes to my body and I feel great.... a little sore but great!
try a dvd by zumba or another trainer you like, and mix it up. Don't do the same routine all the time. Confuse your muscles by having a different routine every day.
