And after (over)training if your cortisol is too low- you will feel like shit.

For 60 min bit- I disagree, strongly. OK for experienced athletes, lifters their body adjust a bit so they can train little bit more like 10-15 mins more, more than that is not good. Its not that others said it- my own research and my own bloodwork confirms this. And if you have to train more than 90 mins- than you should take a week off sometimes to allow your hormone levels to recover.
How does this fit with the training of Olympic weightlifters? They train up to 8 hours a day.
