QS about pushing baby out

Mimikito
I hear many woman push for 45 min or more, up to 2 hours. So my question is; do they push the entire 2 hours like (push-take a breath min or so- push- and again) or do they push and maybe relax for 10 min n then push again? Cause i cant imagine myself pushing the whole 2 hours with only small breaks like 2-3 minutes.
