U.S. Navy Seals Workout

http://www.teenbodybuilding.com/brent2.htm

I'm thinking about trying this (not trying to join any type of military, just as my current workout replacement). Compared to my current workout (run about hour a day, some weights and swimming every other day), I think this could be fun and that I will gain more endurance and strength by the time I am done with it.
What do you guys think about it?

I might give this a try on top of what I'm doing right now (basically everything from weights to running, etc..)

But the swimming will kinda be out of the question though. Maybe take it out for more running?

This is difficult for somebody working on duty like me -___-" but would like to give this a try!
