For the "daily routine" - NO BOOKS! The trumpet daily routine has to be just like the 3 Ss after getting up in the morning: Shi*, Shower and Shave!
Long tones - not too high, not too loud but LONG
Lipslurs - liquid, unstrained, in perfect time
Easy tunes like in Hymnbook range
The daily routine is designed to keep the chops, ears and brains MAINTAINED. It is not there to improve range or technique!
