How do I animate a player without using an animation?

So we all know that if we attempt to load an animation with an animation that you do not own it will not play (for security reasons obviously). But I heard that you can use CFrame which I have attempted and it did not work at all. It made the player move slightly foward. This is an example I want to accomplish: https://gyazo.com/1ff6207676de53acf82c1829dbcd2f45 (this is not a normal animation)
