I am no expert on exercise programs, but it seems you are over doing it on the weight lifting programs. You need to drop carbs in your food intake, and do more duration climbing and descending. Any steps, hills, climbing over fallen logs, rocks, etc. Last hunt I did was in a burn area six year ago. The trees killed by the fire, but left standing were now beginning to fall everywhere. You wind up climbing over logs, under overhangs, on fallen trees, up and down all day long. I am not saying you will hunt in a burn area, only that this type of area is a perfect training terrain. I don't know where you live, but if there are hills where you live, get up early in the morning and run up and down them. Take your rifle, or something like it, and your backpack and about thirty pounds and go as fast as you can. And again, if you can get out West and do some actual climbing and hiking do it! Why do I say all of this? Because what you want to avoid is some twenty something guide who lives in the mountains of Montana and has been climbing those mountains all his life getting a couple of hundred yards ahead of you, and busting an elk herd! By the time you get up to him, the bull is gone. (this is one of my beefs about some guides, but that is a story for another time)
