Last week I linked a site that offered weight-training standards by age, sex, body type, etc. In fact, there are many sites which offer standards and goals like that. Like "A 170 lb. 40 year-old ought to be able to bench press 1.5X his body weight."
I regret any times I have linked those sorts of things because everybody's starting point is different and natural strength and body type vary enormously across people. For example, shorter guys with shorter arms can lift much better than taller guys. While I feel it is essential to have exercise goals to avoid going through the motions, the only reasonable short-term goals are to be stronger and fitter than you were a month ago.
I think it is fun to make 4-month fitness goals, but they should be based on where you are, and not somebody else's (except your trainer's, if you use one).
Look, nobody reading Maggie's (I think) is a Lifter-lifter. They are fitness lifters like me. This is reasonable: How Strong Should I Be For My Age, Size, Height, Weight & Gender?
