I know there is a stickied thread with a list of popular guitar techniques and yes i've checked them out. Im simply further wondering what specific exercises, techniques, and warm-ups you all find helpful to improving your playing.
Spider Exercises are great, they work on your technique, timing (if you use a metronome) and finger strength.
I use simple chromatic scales and spider exercises to improve finger independence and dexterity. I liked the finger exercises that John Petrucci had in Rock Discipline. Those work really well.
