Being able to walk from here to there is essential, and I’m amazed that so many folks talk about disaster preparation, etc. and totally ignore personal physical fitness. <img src="images/graemlins/confused.gif" alt="" />
I’d recommend being able to pass the APFT in the “male 18-21” group. Road marching would be good too, say 12 miles in 3 hours with a 45lb ruck. Beyond that, I’d say work on being able to run a 10k at an even pace, tread water for 15 min, and bench press 300lbs.
With a little work, these are all attainable goals for men in the 20 to 50 age group. For women, I’d move the bench total down to 125% of their weight, and keep the other stuff. If you can achieve these goals, you will be reasonably fit, and live a lot longer too... <img src="images/graemlins/grin.gif" alt="" />
