I see endless posts concerning food storage, gear, shelter, firearms, etc. One thing I haven't found yet is advice on staying physically fit. So i'm very curious to know how some of you are training your bodies, because I am a strong believer that you can have the best gear and knowledge available but some of the first to go in a survival or wshtf situation occurs are the "out of shape" ones. Lots of cardio? Weight training? Crossfit? Do you do a lot of backpacking?
