Keeping your doberman in tip top shape

Well based on the recent thread Doberman Conformation, ******* seems to be a little soft and could use more muscle. I would like to know all your daily exercise routines, weight of your dog, and how much you feed!
Here's *******'s:
Monday's Tuesday's and Thursday's in the morning we go for a short neighbourhood walk. I go to school these days so I don't have alot of time in the mornings. When I get home we normally go over to the college (700 acres) and we go for about 1/2 - 1 hour walk (off leash). The other day's we go for a longer walk/run at the college and normally spend time socializing at petstores or just around town in busy areas. About every other night she go's over to her girlfriends house and play's with her in their backyard. When the weather warms up I plan to increase our walks, but right now I am pretty much a ice cube when I get home!

Food: Go Natural - 1 cup in the morning, 1 in the evening (650 cal. per cup)
Training everyday with some treats, either chicken breast or Wellness Wellbites. Wednesdays we go to obedience so I feed only half her dinner but take a chicken breast. I just switched to Fromm Gold and am mixing that in with the Go Natural. ******* currently weighs 82 lbs and is about 26 1/2" tall!
