Here's a video of Stanley Pranin doing some "yoga warmups for aikido." Many of you will recognize some of the movements, or at least variations, from what you've learned in the dojo. I remember learning and doing what could be called the "downward dog" during classes at NY Aikikai. I have seen, and trained, nearly every movement and posture that Stanley is doing at some point in the various aikido dojos where I've trained.
