Meathead exercises can be great for a comeback player or a pro hit with one of those back to back WO's, Carmina Burana's, Tellemann Psalm 111's, Holst's Planets or such (combined with a same day rehearsal) with a week and a half notice. The coordination is a given, as are the breathing, the aural concept and other skills. We have a choice. We can train like a professional wrestler, or like a professional football/soccer player. Either way, the goal is to be able to give violists and conductors effective head-butts. Critics, too.
