Getting into the Groove (slowly)

Coming back from a vacation after a long string of business trips, I feel refreshed and energized to deal with the grinds of work again.  However, while on vacation and those trips, my exercise levels did drop considerably.  I did my best to train when I could, but in the 3 1/2 weeks I was away from the gym, my weight went up nearly 1.7 pounds, from 190.3 to 192.  Yikes!
