In his "Primal Blueprint Fitness" e-book ( http://www.marksdailyapple.com/primal-blueprint-fitness/ ), Sisson quotes Earle Liederman on defining adequate fitness:
“Every man should be able to save his own life. He should be able to swim far enough, run fast and long enough to save his life in case of emergency and necessity. He also should be able to chin himself a reasonable number of times, as well as to dip a number of times, and he should be able to jump a reasonable height and distance.” (Liederman, Endurance)
Sisson further elaborates his own interpretation of Liederman's criteria:
"For argument’s sake, we could frame Liederman’s quote in practical terms as follows: • 1/2 mile swim • 200 yard run, at full sprint speed • Ability to jump over waist-high objects • 15–20+ pullups • 25+ dips"
My question is how do we modern primal/paleos go about setting our fitness goals, both short and long term? Are the pronouncements of our gurus on this subject worthwhile or merely arbitrary? Are 20 pullups and 25 dips a reasonable goal for everyone, despite differences in age, gender, genetics and body type? Should I train to swim 1/2 mile, even if I have no interest in swimming? How do I know when I'm "fit enough"?
