I'm no fitness expert, but am convinced that simply staying active is more important than any specific routine.
I drink at least a gallon of water a day, quite often more. I suggest everyone gets into this habit.
I hit the gym 4-5 times a week and rotate between chest/back, arms and leg workouts. Some days I decide to change it up and simply do random core or all body workouts. I also check out 20 year old chicks. Keeps me motivated.
Most weekends (not today because of the 50+ MPH winds) I'll hike 5-7 miles and climb a couple thousand vertical feet. If chuckar season is in, I'll often do that twice a weekend. This time of year I just goof around and look for petroglyphs and bunnies and such.
With this informal routine, I have never had any trouble getting to where I need to be during hunting season.
