Your Unrelenting Strides special rule states: "On any turn that you don't use Innate Powers, you may use The Behemoth Rises an additional time."

That allows you to move your Incarna twice, as long as you don't use Smash, Stomp, and Flatten. If you do move your Incarna twice, your Innate Power can thus no longer be used, even if you have the elements.
