Fitting Exercise/Physical Activity into your day

Often I find it hard to keepfitting exercise or physical activity into my day.  I take stairs and walk really fast between buildings, but adding more things to my day seems impossible at times.  However, reading how these busy physicians (http://tinyurl.com/7kfm9zh) fit in exercise provided the additional motivation I need.  Hope you will be equally motivated as well.  Let's get up and move!!
