We're biologically programmed to utilize the valsalva maneuver! Can it be dangerous? Sure. But, more often than not it can help you out on that last rep or so.Originally Posted by quadancer

Odd isn't it?
Back to the original topic:
I find myself grunting/screaming naturally. Admittedly, I don't do so at all times. It happens most often when I'm around a barbelll - be it squats, deadlift, or press. It's a natural response considering the circumstances:
A) I'm moving heavy shit
B) I'm getting tired
C) I'm pissed that whatever weight I'm lifting isn't heavier
So, I scream/grunt. In my mind, my body is being a bitch and it needs to step the fuck up. My scream is the vocalization of that sentiment. Therefore, when I hear someone else scream, I understand where they're coming from. They don't have to be lifting 1000 pounds to scream. Whatever weight they're lifting is sufficiently stressful to evoke a primal response that says, "Man the fuck up."
