I usually just warmup with some classical pieces (
www.activebass.com has plenty of great finger testing pieces), then either learn new songs, or create songs / sounds. I'll be honest; I generally indulge in our leafy green friend for inspiration, which is where I get the basic notes for a song, then when Im sobered, I add complexity and build on the piece. So yea, mainly, just a warmup, a few new lessons, and then song building / technique building. (Took me [what felt like] ages to be able to use my fingers independent of each other, on both hands).
