JBJ,
As an officer in the California Army National Guard, I can tell you about the Army standards:
Basically, the APFT (Army Physical Fitness Test) has three parts, graded at 100 points each.
Pushups (how many in 2 minutes)
Situps (how many in 2 minutes)
2mile run (how fast without being (and I quote: "pushed, pulled, picked up, or carried"
)
You have to get a minimum of 60 points in each category. Although my memory is a bit hazy, for the PU it is something like 40 and SU like 50 and run somewhere around 16:35 or so, if you are 22-27 years old.
It's pretty easy to get the bare minimum. Also, there is a height and weight requirement. I am 5'7" and can't weigh more than like 165lbs or so. I don't remember exactly.
I don't know the exact standards for the AF or the Navy, but I know they are significantly easier
HOOAH!
If you have any other questions, feel free to ask.
