Sore Lower Back From Benching?

[Notorious]

My lower back is always sore as hell the day after benching, even though it rarely gets sore the day after heavy deadlifts. I bench with a pretty big arch and think about pushing my belly out through the whole set, but my ass is always on the bench. Is this normal? Also, does benching with an arch actually tax the lower back in the same way a heavy squat/dead/good morning would, or is it just more of a soreness from stretching?

You're fine. Arching your back doesn't stretch it at all. It shortens it. It's like benching with an arch, and nothing like pulling or squatting. There's absolutely no comparison.
