backward(s) and forward(s)
Back and forth; moving in one direction and then the opposite. Can be used literally to refer to something or someone moving in such a way, or figuratively to refer to a situation in which no progress is made (e.g., an argument). I was pacing backwards and forwards in my room last night, worrying about this morning's exam. The two candidates debated the gun laws backward and forward, but neither could offer a productive solution in the end.
