I see what you mean now. It just looked like you were implying those muscles were useless at first, just took it out of context.
Also I always get leary when I hear "In the real world" because that can be pretty subjective.
I just saw one of "those"guys at the gym yesterday. He had a huge chest and even bigger tits. I actually couldn't stop staring at them.... massive. Giant arms, legs like straws.
I looked at your routine, little too complicated for me. (To each their own of course). When I'm looking at routines I try and keep it a little more simple and taking into consideration;
Amount of time I can spend at the gym may be limited
Availability of the more "popular" machines/weights may be limited since all military gyms are always packed (except airforce ones I've seen)
How well can I modify the routine if I go to the field for an extended period of time
How well would the routine work with a gym with very limited equipment.
How well can I pick up where I left off if I miss a week or two.
Stuff like that. I'm no fitness guru but some routines I've seen you practically need a degree to follow. I have a friend who's workout routine is like a sodoku puzzle with the different weeks and crap here and there. (Not saying yours is that bad mind you).
As for that fellow in the picture, all I see is a guy who can soak up incomming fire for the section of troops behind him and someone who can punch his fist clean
through an enemy soldiers head.
Win win situation
