I start with Segovia scales: i-m, i-a, and m-a. I'll work up to including the other fingerings later. Then I work on a page of the 120 RH Giuliani studies. I'll go through the page 2 or 3 times until my left hand gets sore. After that is sight reading from The Complete Sight Reading Book for Guitar, by Richard Flores. I'll pick a position and go through all the exercises. Then I get into the more musical studies, right now the Brouwer Estudios Sencillos #6, #8, #2, and #3. All that takes 45-60 minutes depending on how dumb I am that day
Following that is music practice.
