Whats the diff. between chin-ups & pull-ups?

[MaxMirkin]

I always thought chin-ups were the ones with your palms facing towards you (and a relatively close grip). But on exrx.net that's listed as a separate exercise. Their regular chin-ups look just like pull-ups, with pretty much the same description. So, is there any difference???

Ive always considered cin ups plams facing you with close grip, and pull ups bring palms facing out with a grip ranging from a slightly wider grip than chin ups to an insane wide grip.

I thought that too, but now exrx has confused me.

I think it's just what they're calling it. I've actually always called chin-ups palm facing away, and pull ups the ones that bring into play your biceps. It may be wrong, but it's just a semantic difference if anything. They are different exercises, though.
