I've tried many things. I used to run 5-7 miles a day but that took way too much of a physical toll on my body. I have used Chalean, Insanity, and P90x workout programs...mostly Chalean, which I loved. The problem there was accountability--nobody to make me stick to it. I walk my dog and take zumba 2/3 times a week when I can get out of work on time!!! Zumba is great because a friend of mine goes too and keeps me on track.
