I have an advantage over some as I live at 6,600 feet A.S.L. and am more used to the altitude. Regardless, hiking from 8,000 to 11,200 with a big pack is hard work. I was in a t-shirt last year hiking in a light snow flurry I was working so hard at it.
I am not specifically training for elk hunting but more of a general, overall fitness. Many may respectfully disagree with my approach, but this is something I am doing in coordination with my doctor. I get regular check-ups and blood tests as part of a larger solution we are working on.
First of all, I have stopped running long distances on a regular basis. My opinion from my research is that the type of trail running I was doing, chasing the 147 lb marathoner from work did more harm than good. It possibly raised my cortisol levels too high and made putting on muscle too hard. I may run 3 or 4 miles once a week, but that is it. Instead I try to perform 30 seconds sprints up a hill at max effort for up to 8 sets, though recently 4 or 5 is all I get.
2-3 days week - bench press, squats, dead lift. I try and max out one day/week.
2-3 days week - shoulder presses, power cleans into a push press, bicep curls, weighted pull-ups.
I also bought an Army 3 day assault pack and loaded it with pea-stone. It weighs about 38lb. I brought it to work today and walked about 2 miles during lunch up a loop with a hill. I will do this several days week. I work in a company with a casual dress code and can wear shorts or change/shower if need be during the summer.
I plan on doing hill work from my home with the same pack - maybe with more weight. I can hike a butte near my home that has a 200-300 foot 35% vertical rise and go up and down like stairs. I also take the pack to the soccer field with some dumbbells and do farmer's walks with the dumbbells and the pack.
I will continue to mix it up. I used to do Crossfit style workouts but no longer do. At my age, packing on muscle is very hard so that is my focus.
I also have a contrarian diet that makes people at work cringe. I eat an ancestral Weston A. Price diet similar to paleo but not quite as strict. I eat lots of saturated fat and shoot for 50% fat intake. Bacon, sausage, eggs, coconut butter, coconut oil, coconut milk, real butter, raw unpasteurized politically-incorrect milk from the farm, grass-fed beef along with vegetables and fruit. I take the FDA food pyramid and flip it upside down. I avoid grains and legumes but do eat them on occasion, often when travelling for work.
Though the focus of this thread has not been nutrition, for me, that is a big part of how I am living my life these days and it is part of how I am getting in shape. I am new to the forum and don't know the average age. What might be appropriate for someone 22 years old might not be for someone 62. For comparison sakes, I am 42 years old, 5'-11" @ 178lb.
