Lets come up with a test of basic fitness.

I honestly think the PST requirements for BUD/S is a pretty good basic fitness test (depending on your defition of fitness):

500-yard swim using breast and/or sidestroke in less than 12 minutes and 30 seconds
10-minute rest
Perform a minimum of 42 push-ups in 2 minutes
2-minute rest
Perform a minimum of 50 sit-ups in 2 minutes
2-minute rest
Perform a minimum of 6 pull-ups (no time limit)
10-minute rest
Run 1 ½ miles wearing RUNNING SHOES and SHORTS in under 11 minutes

wow ... i just noticed that they changed the running requirement to running shoes and shorts! sweet!

But anyways, this is just the BARE minimum to make it into BUD/S ... so I think its a good indicator of what basic fitness is.

P.S. Crossfit is sweet, and i love it.
