Bench presses are measuring your ability to bench press. Iq tests are measuring your ability to do IQ tests (and not your IQ)
Edit: just to clarify, the fact that you can train to improve an IQ score means that it is not a very good measure of innate ability. You can't really talk about "having an IQ", all you can say is that you got 130 on your last IQ test, a bit like how you might tell someone what you got for your SATs.
