My ultimate goal is 16th's at 180 bpm. But no matter how often I practice fast songs..well, it seems I've hit a plateau that bodybuilders hit..I'm just not gaining anymore. I've taken up guitar as a hobby and read an article on increasing picking speed, where you raise the string up at certain areas on the fretboard to increase tention - making it harder to pick, resistance training - and applied it to bass. Hasn't really helped a whole lot. Any tips?
