Before the 45° hyperextension became so popular, this was the premiere exercise to strengthen the spina erectors, unfortunately horizontal back extension machines are very uncommon today, but if you have one I suggest utilizing it.
It’s a simple exercise that can be regressed or progressed readily.
Once you’ve gotten strong with Bodyweight, add weight at the chest or behind the head.
This exercise does work the glute deals at the same time, you get glute strength with back strength. For that reason it’s usually better to program these on a lower body day.
