Would we be larger and stronger or smaller and slower?
Well since Jupiter is a gas giant you really have nowhere to be "born" at unless you are in a ship passing through the atmosphere, is that what you meant?
I probably should have stated my question a little better, how would we (humans) change if we lived on a planet with the mass of Jupiter?
A planet the density and mass of Jupiter? Nothing solid can exist at that density. However, if you put a thin shell around Jupiter, and lived on the surface, you'd weigh 2.5 times what you weigh on Earth. It is conceivable that humanity could adapt to that, but they'd end up as short fireplug-shaped dwarves with much thicker bones, larger joint surfaces and larger muscles.
A planet the mass of Jupiter and the density of Earth? You'd weigh roughly 300 times what you do on Earth. Human bones/muscles cannot adapt to that. We'd probably look more like starfish - something flat and somewhat flexible that can crawl slowly along the ground.
(useless fact of the day - Jupiter cannot get much bigger no matter how much mass you add.)

That's more what I was looking for, I know it's not that serious of a question which is why I put it under free thoughts. I am trying to figure out what type of planet would create a humanoid species to be larger and stronger for something I am working on.
