Hind Legs

We also need to do the same with the back legs, but they can be much more exaggerated than the front as they're more flexible and use more power to push off the ground. Again we'll need to scrub through the frames and judge where the legs is furthest forward, which I think is frame 6 for the right leg. Start by selecting the "rt_rearLeg_CTRL" and Rotate X back to about -30, and Translate Z forward slightly.

And frame 12 where the legs are kicking out, Rotate X forward so the leg is higher and Translate Z back so they are further out. 

And now we begin the same process for the left back leg. For the left side, at Frame 2 where the leg curls up and forward before kicking down, select "lf_rearLeg_CTRL" and Rotate X back and Translate Z forward.

The left back leg kicks out again at Frame 11 just before the right leg falls back down, so Rotate X forward and Translate Z back, again no need to worry about exact units.
