Warm-up sets and length of workout

[ZZuluZ]

In terms of cortisol release (and working out 45mins-1hour) how do warm-up sets factor in?

I like to do quite a few, to warm up my muscles and potentiate the nervous system (I feel I lift more after doing 4-5 warm-ups) but I'm wondering if I should factor those in terms of workout duration?

Thx guys,

I usually warm up with 1 set then hit it for 3 sets. I don't count the first set of warm-ups in my total sets. But usually only do a warm up set on the first exercise for each body part.
