Why does it seem like we can improve our bench press, minutes-per-mile, or alcohol tolerance much more than we can increase our IQ? Can a person with a 100 IQ get a 120 score after training? 130? Seems quite believable to me.

Training a limited system to be more efficient at a specific task is certainly possible; you can improve at any skill - that's what learning is. Learning skills absolutely doesn't translate into improving your overall mental acuity.
Isn't that kind of analogous to muscles though? If you practice pushups, it won't help much with your pull-ups.

It's not analogous because muscles aren't a limited system. You build new muscle tissue This is extremely rare in animals and is a consequence of humans having varied roles and the danger of starvation - it lets your body cheap out on expensive muscle tissue that would be unused

But, don't you think something new is being built within the brain? Interesting re: animals.
