I did some dancing today

I did some dancing today, so I felt pretty decent.  However, I feel nervous about having an exercise regimen.  Still, I have yet to exercise strenuously.  I guess I could walk for the moment.  I believe that walking would tone up my entire body, especially my stomach area.  I want to lose weight and eat healthy.  I want to be healthy.  It has been a long time since I have been of a healthy weight.  I want to just be healthy and maintain good eating habits because I have no clue how much I want to weigh.  I just have to get over it.
