Nah, not really. What you'll hear is either
"if you're spending more than an hour in teh gym, you're not working hard enough"
or
"dood, those cortisol levels will sky rocket and all your gains will be shot"
Just listen to your body. I've had great 25 minute workouts and great 1.5 hour workouts...just depends on what my mindset is, how far I want to take myself to puking level, and what movements I'm (or you're) doing. The deal with cortisol is it can be combated with longer rest sets, carbs during workout, and a higher workout capacity.
