Manipulate animated character

So here I have an animated character, which has an idle animation, walking, running etc animations, however I'm wondering how I make my player bend at the waist to look up or down depending on how he's looking, so a specific euler Y angle.

If I take the animation off, he's able to bend fine and look up/down, however I need to be able to manipulate him so, WHILE the animation is running. Is there an easy way to do this?

Here's what I'm using ^

 

Use LateUpdate to overwrite whatever the animation does before the frame gets rendered.

 

Awesome, works great
