I can do shoulder and arms in 45 min, including set up and break down. Torso and legs can each be done in less than an hour. It helps to have Nautilus machines (MedX would be good too.) I like Hammer as well but they take longer. The bottom line is train as hard as you can then get the fuvk out. Rest, eat, go study, etc. No reason to spend 2 hours at it. Testosterone levels start diminishing and cortisol starts increasing after 45 min to an hour anyway, that is an indicator.
