Solo is a workout that will hone your combat skills and ask your body to go through a series of highly coordinated movements. None of this is by accident. Complex moves challenge fitness by recruiting many different muscle groups in a fluid dynamic and they force the brain to restructure itself by learning new ways to move the body. The benefits then are felt in many different ways that include both physical and mental aspects of fitness. And, of course, you know you want to do this with EC, right?
