legit question here

Will doing situps/ crunches leaning off of an elevated surface, as in, being able to lean back further than 90 degrees, help in exercising your core or just fuck up your lower back?

as long as your back is straight, you'll be fine

Depends on how strong/weak your back already is. As well as how heavy you are.
