I've heard of something called "Seal PT" - Now, I expect that most guys who really did that in service of our country don't bother to hang out here, but my buddy was talking about a variant done with a section of log...  Pushups, etc...  Any idea what he was talking about, and any specifics?  Those of you in any level of service, what did your PT entail?  

I suspect the average arfcommer can't hack it (See the bicycle to work threads) but lets hear it!

Ever watch the BUD/S Class 234 videos from the Discovery Channel?  Thats real SEAL PT.  Stew Smith has a program called "12 weeks to BUD/S" and its pretty intense.  Other than that, Crossfit is really popular with a lot of them apparently.
