it is not black and white the way you are doing it. you have to start at the beginning...for any exercise, you start by breaking it down into small components
does he know down? Do you have a marker word or use a clicker? put him in a down. Stand toe to toe in front of him. Lure him with food into a sit, saying here or front or what ever command you will use for a recall. Reward the sit/front with ONE word or click and food....not a string of words...being close to him at the beginning will teach him to be close. Repeat, repeat, repeat - muscle memory.
I am sure there are other ways - I like this one..
