Never. Would you work you triceps BEFORE you bench press?

You also want your biceps to be in their stongest position as well. Here is Arthur Jones had to say about it the first bulletin he ever published (by-the-way there is a lot of very good information in those old bulletins):
The Latissimus muscle; most bodybuilders perform exercises for the
Latissimus muscles with a wide grip - under the sincere, but badly mistaken, impression that
such a wide hand spacing provides more "stretch" than would be afforded by a narrower grip.
Secondly, all conventional forms of chinning and "pull-down" exercises for the Latissimus
muscles involve working the upper arm muscles; and as noted previously, the weakness of
these arm muscles prevents the trainee from working the torso muscles as hard as he should
for best results. This being true, then why do most bodybuilders work their Latissimus muscles
with the arms in their weakest possible position?
We have already seen that the arms are strongest (for bending) when the hands are twisted
into a supinated position; this being so, then why make the arms any weaker than necessary -
when they are already too weak for the production of best results even in their strongest
position? Yet most bodybuilders do exactly that; they work their Latissimus muscles while
keeping the arms twisted into their weakest possible position.
By simply giving the hands the maximum possible twist in the direction of full supination, the
bending strength of the arms will be markedly increased; and it will then be possible to work the
Latissimus muscles much harder than it would have been with the hands in a pronated position.
