Glad they helped.
I've pretty much came to the conclusion that people who sit at desks all day basically beat up their joints more than guys working in some kind of manual labour. When going to universtity and working (3 part time jobs, all of which required prolonged sitting) and then leaving uni and working full time (sitting at a desk), my posture changed quite dramatically. It was the 'real' cause of a chronic shoulder injury. Although my stupid training program only made things worse. Before university I would just sit down during School and was very active out with school - never much into computer games or anything.
Also, Chiropractors and Massage Therapists and other various experts are making a fortune from my work place. Men and Woman around 30-40 years of age all hobbling around as if they're war veterans or something. All they 'do' is nothing, ya know - it's very bizarre. One of the directors in my company pays a physiotherapsts and chiropractor regularly to sort her aches and pains, and get's a Personal Trainer to help her lose weight (clearly, none of it is working). That's exactly why i'm going to get certified - try and get people like that to consolidate all their fees into one fee and i'll fix everything

I mean, if the trainer knew how to design a program around her posture then he would know to stretch whats tight, strengthen what's weak, and bang on about making an effort to sit in good posture and move around some more, which would be the answer to allof her problems which, right now, are taking 3 seperate payments to 3 seperate experts, and it's not even working. It's crazy.
My work place has some pretty extreme examples though - people who sit all day and sit all night, and sit all weekend, and have done this most of their lives.
Ok, couldn't help but rant there. If you follow the advice of those articles, you'll do very well. I would actually say that about everyone, not just 'desk jockeys'.
