Walking Pose

Hello, I am trying to make a pose of my sim walking. I modified an ea animation to my liking, but it is just one that walks in place. I have tried to make the pose actually move forward but every time I try it looks really bad and the key frames are confusing so it just looks like my sim flies forward a bit and then jumps back to the origin point. Not sure if that makes total sense, but the point is I have the animation I just need it to move forward.

Could someone please to me explain how to do this or link me to a tutorial. Not just a blender tutorial about animations, but one that actually has a section on walking Thanks!
