Here I'll be discussing some excellent exercises that can really help your playing, but look, sound, or feel weird. Many of them are familiar, or make sense. We hear about them, and nod approvingly - and go on doing something else. Others just don't seem like they would be helpful, no matter we hear about them from amazing players.
I'm posting each one as a comment.
Take the tittle as a dare, and try out these suckers.
