If u have lots of stool (fecal loading) that's dry and hard, are u at higher risk for perforation if u bend down, do crunches, or contort the torso?

Probably not. Unless you have such severe fecal loading that you've basically developed an obstruction and subsequent severe intestinal dilation. And the high risk would be a blunt force trauma/"blow" to the belly rather then bending. If it's reached that point, you'll probably already be in the hospital or own your way there.
