I read something that made sense once, but don't ask me where.
You are supposed to wrap your thumbs around the bar to prevent the bar from falling onto you if you lose control.
I'm looking at the "Bench Kings" article (not alloywed to post in the appropriate topic for some reason), and I see that they don't do that.
I personally prefer the grip shown in the image with thumbs running parallel to the bar. I've successfully unlearned that cuz I heard it was safer, m'kay?
Any thoughts? Does it matter? Can I go back to benching my favorite way?
