I actually have a job that requires a lot of lifting and moving moderately heavy objects (I put out stock and merchandise at a department store). I have no trouble throwing around luggage and large boxes of shoes. However, if I'm home or out somewhere and something heavy needs to be lifted, I do pull the "I'm a girl and thus weak so you do it" card if there are any guys around.
Unless the men are taking too long or cannot do it themselves (most of the guys I know are pretty weak actually). Then I tell them to step aside.
