stay level

on the big reach get the racquet squared up

both elbows up

on the 2 handed backhand finish we like both elbows up as you rotate over your shoulder

track it in

you want to track the incoming shot all the way into the center of the racquet

spin out and run

when the lob goes up with some depth you spin out and run back to get behind the shot

more both down

again you want the racquet and the back knee below the incoming ball
