Alternate / Economy picking exercises

Stuff like that.

Practice slowly with a metronome using a clean undistorted sound.

You're better off asking the electric guitar forum in relation to techniques and excercises. This forum is more focussed on music theory.
And no, Guitar Hero will not help. Even on expert. Really.
