‘Newbie routine’ is an unfortunate name. The basic routine is not just for beginners, neither there is a time frame past which it is mandatory to move from that routine to a ‘more advanced’ one. The idea is completely different: the newbie routine is a well rounded routine that will work girth, length and EQ. You should add more stretches and jelqs as time goes by, but not necessarily move onto different techniques - since when the basics are working, keep doing them.
A lot of people get nice gains from the newbie routine, than in a hurry for gains moves onto hanging or clamping or whatever, just to discover that the latters don’t work as well as the manual basic exercises and often have more issues (and cost a bit of money too).
