I'm 5'8". I started at 91kg (~202lbs), fat & weak (could only do 7 push-ups). Trimmed down to 71kg (158lbs) through lots & lots of running. Then I got into weight training (early last year, seriously since October 09) and I'm now 81kg (180lbs) with a lower bodyfat percentage than I was at 71kg and much more muscular.
At 91kg I was pretty much invisible and ignored. Down to 71kg, I was always included in social events. And now, guys are showing me a certain level of respect that I have not seen before, and women check me out more often or find excuses to give me shoulder rubs (not so comfortable when it's at work

).
Of course my social skills & Game were getting better at the same time my body went through those changes, so I can't say it's all the body. However, the confidence you get through that transformation shines through and people take you more seriously when you've demonstrated such discipline and bada$$ery in training - qualities they don't have. Most of my social circle consist of dance venues, and there my athleticism, high level of fitness & strength & energy show. People give you respect when they're all puffed out from a fast dance and you're still standing straight smiling. Girls are turned on when you can effortlessly pick them up off the floor and press them over your head (or flick & toss them around), while other guys struggle to do so.
I still have a long way to go with working on my training & body, but it's paying off nicely.
I think strength training should be a part of a DJ's lifestyle. You know the quiet confidence that a DJ exudes effortlessly, which is so irresistible to women? I could never quite figure out how to achieve that consistently, until I started this:
http://www.sosuave.net/forum/showthread.php?t=169625 - the 20 rep breathing squat, which is one of the hardest exercises in weight training. After you've conquered a set of that, you feel like you've defeated The Beast, and when you go out that night, you're right In The Zone.
