Mine are taking 30 minutes or less, probably because I take about 45 seconds between sets and 2 minutes between exercises.
I don’t know what CT recommends in general, but am doing it this way because
(1) rest times are hard for me to wait through, so I’m always chomping at the bit to get to the next set or movement
(2) I am trying to lean out so the shorter rests work for my goal.
I’d be interested to hear how CT recommends manipulating these times for (x)purpose.
