Moving Torso Moves Whole Body; Not Just Upper Body

Hey! I am trying to make a walk animation for a character, but when I want to bend the torso that it’s slights bended over, it just moves the whole body. Now I custom rigged all of this myself, and I might have done something wrong. Or I may have forgoten to do something. Here iare images of all the welds and joints of the body:

Everything but Torso

Torso

If you can help me please do. I don’t think a video is necessary. And I will repeat the question one more time in case yall forgot: The torso moves the whole body, when I want to move only the upper part of the body
