1) When I bench, should my butt be off the bench and my weight centered on my chest?
2) I'm currently doing 175lbs 6x3. My triceps seem to fatigue whereas I feel hardly anything in my chest, there's a considerable "pump" in the tris. My grip is already fairly wide -- pinky finger on the 2nd ring of the bar.
i.e., feels like my triceps are doing all the work
