Since I retired 2 years ago I'll usually take a couple of hikes a week into my elk and deer hunting areas.  I only live 10 minutes from my elk huning ground and 30 minutes from my deer area.  That and living at 6500' helps also.  During the off season of deer and elk there is rabbit, geese, ducks, fishing, and a couple of other hunts to go on that usually keeps me up and going not to mention the yard work on a half acre that keeps me bussy. 

A few years ago since my mid 20's I lifted heavy weights to build muscle. I'll be 40 this year and my workouts have changed to a lot of what Cameron advocates, cleans, squats, presses, with reasonable poundages (not ultra heavy weight but not light by any means either) followed by intense cardio, 1 full minute of jump roping followed by one full minute of hitting the heavy bag two to three times per week. This keeps me in shape to hit the trails chasing elk and deer in steep country and able to pack em out if successful. I like what Hanes preaches.

I do alot of cardio, run 3 times a week and hike with weight added to my pack. I having a pretty physicaly demanding job so i dont do to much strength training anymore, that and i have arthrytis in my right shoulder.

I like to sit in recliner and watch hunting shows. You know the ones where the hunter looks like he can't walk a 100 yds and kills some record class animal eating at a feeder. Then get up and go run 3-5 miles, mountain bike, or put weights on a pack and hit some hills.

Great for you all! Keep it up. Have any of you tried P90X? I recommend you all try it! I started it over 1 year ago, and I do a form of it still today. I didn't really care about losing wait, I just wanted to lean out and get in shape for hunting. Whatever works, works. So many different things to do, or try. I ran bleachers last week but woke up with a swollen knee, so I will be going back to doing the Plyometrics routine from P90X which if you think your tough you should try along with the leg routine and get your legs and lungs in the best shape of your life!

I'm not the mountain goat I used to be, but I try and help get the legs in better shape by walking and doing some coyote hunting, scouting deer locally, etc. beforehand. I hunt the exact same areas now year after year for Elk and know what to expect. A big plus for me on the "breathing part" and all is to get up there at least two days ahead of time to adjust to the altitude, in my case about 7500' or so I think. Seems to take me that long now that I am older and still a smoker, and it just makes me feel more comfortable, less fatigued in canyon climbing etc., and easier to get up early each morning to get out of camp. More time in the woods is great anyhow... ;-)
