I implore you to first read/listen to a book called "Training for the New Alpinism"
https://m.media-amazon.com/images/I/81nW+2St3jL._SY425_.jpg. If you're dumb like me, audio book and listen to it a couple times. You will gain an very in-depth understanding of how you body functions in the mountains, what it needs to function, and ways to gain those functions.. fast twitch, slow twitch, zone 2, strength without muscle mass, how when and what to eat (yes elevation matters, we can not break down proteins after a certain elevation) etc. Once you really understand those things you can basically pull from a lot of programs to be optimized.
As stated above the "programs" don't sell because they are not sexy. They are extremely boring and take 1500+ hours of slow boring training a year.
Another issue with cookie cutter programs is we are all extremely different. If you were in the womb and born at higher elevations (10,000+) you have a larger heart and lungs than someone born at 10' elevation. Do you live at elevation vs sea-level? Body type is a major factor.
@Braaap is absolutely going to destroy me up a mountain, hes built to, Throw 2 elk quarters and camp on each of our backs and I probably have the advantage. Not sure about everyone else but 2 quarter and camp on my back makes up for about 5% of any given hunt for me. So I have to heavily focus on zone 2 training. As where the little fn mountain goat that can sprint up the mountain and never breathe hard could probably focus more on slow twitch, heavy muscle work.
Save time, money and wasted training by reading the above book and go from there. Anything is better than nothing but if you are really wanted to be optimized you're going to have to perfects your physical strengths and take your weaknesses to strengths.
