My gosh I so totaly agree that exercise work when you feel tired and down. I try to get a small but still good workout when the kiddies sleep. Makes my afternoons so much better. Sometimes, it's just to get that motivation up that's the tricky part. I am soooo longing for my old school areobics classes. My gym stoped offering them and I can't find anything else I like or with hours that works for me.
