Thanks guys for all the comments. I have been working on cardio four to five days a week now for five months. Always at least 50 minutes and up to a hour and a half of different exercises including elliptical,stair climber, treadmill, biking, hiking, and hiking with a 50-70 pound pack. I've personally lost about 10-15 pounds in preparation for this hunt. I have all the lightweight gear I will need for this hunt and a Kifaru UL hunting frame and a Nomad bag which carries the rifle in a center pouch like a eberlestock. I am just trying to prepare myself as best as I can. Thanks.
