Prone Pridges hurt back?

[Subsistence]

My lower back is sore on supine bridges before my abs are. Is this an issue, and if so, how can I fix it?

Squeeze your glutes and your abs. It forces the pelvis into a neutral position and takes the stress off the lower back, putting it on the abs where it belongs.

Try not to arch your lower back.
Even if you do the prone bridges with a curved spine, it's okay.

^^^ This. If your low back is sore, you are flexing and extending it. Lock it in place and drive your hips up using your glutes.

And why would your abs get sore from supine bridges? Do you mean planks?

I did mean planks...sorry
