Exercise

Okay, what's the deal with exercise?  I thought walking and chasing after anything that moves outside was considered exercise.  That's all I need.  So, I always pick up one of my loofah dogs and hit her on the back of the leg if she is doing sit-ups or on the ankles if she is doing crunches.  One day she gets the bright idea to have me lie on my back and lift me up and down so I can do sit ups as well.  Very nice.  No thanks, too top heavy and too much work.  Let's just go for a walk and work off the calories that way.  Besides, when are outside, there is always so much to see and explore.
