My motivation for working out. I want to avoid something like this happening to me. Yes, yes, what are the chances...
I can't find it right now, but the study just compared muscular men to averagely muscled men. I don't think they looked at how their sample became muscular or what kind of sport they did, they just looked at muscle mass. I think it was quite a bit of muscle mass, something you don't just get from a general lifestyle. So, they compared men with lots of muscle mass to men with an average amount of muscle mass.
I'm not saying one routine or sport is better than another, but when you're objectively looking at muscle mass, it is healthier to have more than less, and the more muscle mass you have the stronger your bones will be, regardless of how you got those muscles. I wish I still had the research paper that looked into this.
For the first point, I agree with the article. But I think that it would be nice to see how fit the girls are. Girls that are skinny-fat (those that look skinny but you can see the fat from behind popping out of their jeans) would prefer a body like that one in the article, Brad Pit. But fit girls, that somehow know how hard is to keep a body prefer more... mmm I don't know how to say it but not ala Frank Zane or Zyzz but just a touch lower.
But then it bring us to point number two. In my case I focus my training on core and legs. I don't have massive arms, some girls don't put attention to that, they guys are the ones who care to have big guns, so train the muscles girls like.
