I see an analogy with children, some have a better coordination than the other. They are young and they didn't have that much time to practice, so they start with something they are born with - genetics. The ones that have a better coordination have a higher probability to be good in sports. If it's not the muscles or physical predispositions, respectively limitations, then the brain plays the most important role, how it's wired. And you can't train your brain to have a higher IQ than you naturally have. You probably can raise it a few points but not 30 or 50 points. Practice, extreme motivation and persistence can bring you a few steps further but it can't make of you something you're not. That's my opinion.
