Scales.

I run a few of the two octave scale patterns, single note picked, in different areas of the neck, grab a few of the same chord in succession up the neck, say, an F7 in each successive possible position, as quarter or 8th beat chords and that's it, let's go.

I think that having been a Trumpet player, where warming up that big chunk of metal is actually likely more important than warming up the chops and muscles, has always led me to believe that "warmup" excercizes on the guitar or the keyboard are way overblown by some folks.

Just do whatever YOU need to do in order to get ready to play -- and know that if you're spending an inordinate amount of time on it, you're not doing it to "warm up".
