I am looking at fitness plans to do this summer to get in shape for backcountry elk hunting. Many are geared for flatlanders. However, I am lucky enough to live in the mountains at altitude (7200 ft). I have trails out my back door. I don't really see the point of doing a million stepups in my garage, e.g., when I can get right on the trails out my back door. Does anyone know of fitness plans geared for those lucky enough to already live in the mountains?
