Other than elite athletes, what is weight training good for? Most of my friends that are exceptional athletes rarely lift, the ones that lift and are big are uncoordinated, unathletic, unflexible, out-of-shape useless tools.
It's definately not to look good because it's been proven that sprints and bodyweight excercises will build a proportioned, functional body that is far more attractive to the opposite sex than a deformed, out of shape, bulked up, unathletic weight lifting build.
It's not for improved real-life functional strength for work etc. Most weight training simply does not carry over to real world activities and most really strong individuals such as farmers and lumber jacks never touch a weight.
So why do it, if the only thing you get from it is being able to say you lifted 10 more pounds than 2 months ago on a certain lift? In those two months you also gained a little weight, look a little worse and are a little more unathletic. YES!! Just what I want!!
