How often do you train with barbells during a session

tough one but two on back day which is bad lol bent over rows and deadlifts out of 6 exercises, maybe one on chest day incline barbell out of 5/6 exercises, two on leg days squats and RDL out of 6 exercises and arms day is usually 5/8 because of forearms and supersets make most of the exercises hence why 8 exercises on that training day
