Ok so this link basically leads to reddit thing about him working out for 7 hours, but I clicked on it because it popped up on my facebook.
Here's the beginning part of the article:
I once heard a story from a friend of a friend who worked out at the Lakers facility. Kobe Bryant was there, too. Apparently, while this guy was working out, Kobe spent the entire time hypnotized watching Animal Planet videos of lions and cheetahs hunting down gazelles and mauling them. Now, we have no idea if that's actually true, but it SHOULD be true, and that's all that matters. Kobe's more fun when you imagine him as a sociopath.
