I am using Blender 2.8. I have been trying to make a character I just rigged dab (because it is a simple movement), but early in the video my character's hand spins 360 degrees along the Y-Axis in the frames between my two keyframes. I have tried rotating the final position 360 degrees in all directions, but the hand is still spinning in a circle. Why, and what could I do to prevent this? Here is the render. It is a short video, so I couldn't attach it to this post. Thanks for your help!
Edit: Here is the *.blend file.
