It is definitely hard getting back to being active.  You begin to realize how sedentary you really were.  I always called it relaxing which was usually accompanied by eating while watching tv.  Not that it is bad to have a snack and watch a movie or tv but not being active during the day before that , was very detrimental.  I feel so good right now, even after my little walk and bike ride.  I also feel like I could do more but since I will be doing the same thing, later this afternoon in the hottest part of the day, I am allowing myself to chill until then.  Just something I was thinking about.
