I'm pretty good at coming up with a practice regimen and then basically ignoring it because I get distracted and noodle. However, with the addition of a couple of ideas and things I've been reading, I've generally been sticking with a (sorta) daily schedule. The noodling eventually finds its way into each session, but I try to get some work done. I have anywhere from an hour to two hours during the week and double that on weekends (if I am not obligated to do something and if I get up before everyone.)
It looks kind of like this:
Warm-up - this varies by week. The key is not tempo, but accuracy and feel. Relaxation. I'll try to get some rhythm in here.
Old solo - one that I've previously learned and that I attempt to get up to tempo. Two days a week, I'll try to really push the speed. I'll try to get some rhythm work in here.
Licks - I'm either playing an etude (like Anthony suggests in his book) based on licks I may have learned from various solos in something I've pre-constructed or I break down the old solo ^ and try to play as many licks as possible in all keys.
New Solo - work on something I've chosen to learn by rote. I work on this until I can do it without a playalong (with just a metronome) and then try to work on speed. I've ignored much of the rhythm kick stuff that may go on in a song until recently....so I've been trying to work on that as well.
New song - learn the head as well as I possibly can, learn changes, try to compose an etude for the above.
Free play - non thinking get my fingers moving noodling.
Saturday or Sunday is basically my reset day, where I attempt to set the agenda for the coming week.
Timing for each of these is kind of tough. I try to keep the bulk of the practice between the middle three things in a session. So if I have an hour, about I spend about five to ten warming up, forty to forty five minutes on the middle bit, and end off with some playalongs. If I'm sitting on the couch after dinner, I'll noodle through stuff.
Curious as to what others are doing who have limited time to practice.
