How does deadlifting hundreds of pounds not mess up someone’s back?

Question

It seems that this exercise goes against the wisdom of “lift with your legs.” Why is that?

Answer 1

Its a combination of bracing as other have said, but its the whole posterior chain really. Hamstrings, glutes lats all play a major role. It just seems like you’d throw out your lower back because when you finish, you’re straightening out at the top but really thats just the last 20% or so of the movement.
