No one approach is the be all and end all. A variation on that is this... 1/3 up. 1/3 down, 2/3 up, 1/3 down, 2/3 up, 1/3 down, 1/3 up and all the way down. Repeat til you can't go any more.
I will do that once in a while.
As I go heavier I will do fewer reps. About once a month I will 'cement' the gains with a high rep exercise session.
I go to exhaustion once in a while when I feel like it. Not often.
