The quickness of Akuma's U1 input

So I recently started playing SSFIV, I got it the week of thanksgiving and I got myself a fight stick in the beginning of December. All of my friends have commented how I’ve gotten rather good rather quickly. The only thing I have trouble is the quickness of Akuma’s U1 input. I can’t seem to pull it off without people seeing the jabs or anything. Is there a video somewhere showing just how lightning fast ones hands have to be moving to do the input without any signs of it? Thanks in advance.

Also, I couldn’t find a thread like this on here so I made this one, if there is one I apologize.
