For some reason my rig's targer pole isn't working properly. I was trying to practice rigging poses by using an image as reference, but I didn't know why my pose was limited and it wasn't deforming cleanly or realistically. I tried to clear the pose using alt s and alt r and alt g but for some reason it isn't working.
I tried using forward kinematics but my rig seemed to deform like paper, but I'm not sure what to do to make it move realistically
