Muscleman Update 2: Anubis Preview (Patreon)

I've fully rigged and corrected the muscleman and given it it's first head: Anubis!Seen here is an animation test, to test out my ik rigging. If you don't know what that is dont worry it is just a certain way to control the rig for animation, for example, keeping certain body parts still while others move as seen above.Problem here is Blender's ik system is a little twitchy. I can't seem to figure out how to get the arm from jumping around like seen in the left shot. I can't figure out how to get the arms to stop doing that. I've tried using limits and poles, I've tried pre-bending but there's always a problem. But, at least, It is functional for poses and basic animations.Attached is a better quality version than seen above.
