Sheep and ibex hunts are won in the months before you fly. No outfitter, rifle, or optic makes up for legs and lungs that aren't ready for the country.
Start with time, not intensity
Twelve to sixteen weeks out, begin building your aerobic base — long, easy hikes with a light pack. Volume first. You're teaching your body to work for hours, not minutes.
Load the pack
Progress to hills and stairs with a weighted pack, adding load gradually toward 30–40 pounds. Downhill is where hunts hurt people — train the descents on purpose to save your knees on the mountain.
Don't ignore altitude
You can't fully train for thin air at sea level, but strong aerobic fitness buys you margin. Arrive a couple of days early when you can, hydrate hard, and pace yourself the first day.
Shoot tired
Practice from field positions with your heart rate up. The shot you get on day six won't come off a bench.
