I'm 37. Developer. I had suffered lower back pain for five years, sometimes severely. I started doing just 20 pushups a day and it is completely gone.
Just one data point, I know. But since that data point is 100% of me, I'm sticking with it.

Planks build core strength and the lower back is part of your core.
I would add squats to the pushup routine (even unweighted). They will develop the quads and glutes somewhat.
