Just join a Crossfit gym if that is an option. Once you nail the basics of that down, you'll "own" it for the rest of your life. It truly is a "physical education".
Having said that, I am of the opinion that a backpack hunter is most likely better served by a program that incorporates "periodization".
Stew Smith (How to Train like a Navy SEAL) gets folks in condition for a living, and his program is to mostly lift starting around the first of the year, using template that looks a lot like Mark Rippetoe's "Starting Strength". Most folks plateau on that program in a couple months, try to maintain that strength level and start doing Crossfit and some runs. Learn POSE/barefoot running form. Get the form nailed down, then start doing 400/800m repeats. The form is easier to learn if you start running fast first. Taper the Crossfit back and ramp up the distance on the runs up until hunting season. You are trying to maintain strength/GPP while ramping up cardiorespiratory endurance.
Do what you can when you aren't hunting. First of the year, start over. Also, you can't outrun/lift schidt for food. Paleo/Zone is optimal, the Zone Diet is a non-negotiable. Learn and implement it.
I'd wager a tidy sum that Crossfit's "neuroendocrine response" will raise your HDL at least ten points.
