Another yoga question

Amo_Angelus

Ok, so as I said last time, I have a yoga app on my phone, basically it has routines to run through as well as instructions for different poses. I have three routines for my ability level. I put one on last time and struggled with on post, but as a whole the routine was ok. So here's my question, is it better to stick with the same routine until you master it and then move on, or is it better to do different routines. So do 1, then 2, then3, then maybe 2, then 1 and so on, or is it better to master 1 before moving onto 2?
