Sweatin' While I Work

I do not work out very often.  I tend to go in spurts.  Lately, I walk or do Zumba.  I haven't been doing Zumba for long but enjoy it.  It is a lot like dancing which does not seem like exercise to me.  I notice when I do work out my energy level is much higher.  I don't get as tired during the day but I do get hungrier.  I am also more fatigued at night.  It is easier to go to sleep and I sleep better.  I am trying to work out more often because I do enjoy the benefits of it.
