Running and lifting 4-5 days per week. Usually just a maintanence program during the late winter and start hitting it hard about May to get ready for the upcoming elk season. Use to run marathons to stay in shape but decided I didn't need that much trauma to stay fit! The area we hunt for elk is STEEP!! The trail is at 9000' and we climb up to 11,000-12,000' every day. That'll burn the calories off!
