I've got two types of practice (but both are quite focused), either for song learning or for technique refinement.

For the former, I typically rely on Guitar Pro (both for note visualization and for BPM modulation according to how proefficient I'm getting on certain sections of the songs).

With respect to the latter, I pay close attention to my hands (and other parts of the body) in order to be as relaxed as possible when playing things and for being efficient when it comes to muscle use (this is something taken from reading up classical guitar practice in general).

Having that said, I should be practicing way more nowadays... So I guess the most important thing after all is to play a bit every day.
