This video series was created to provide foundational training for fencing with the medieval longsword. The basic principles you'll learn in this course are intended to prepare you for practicing the art of the German style/method of longsword fencing (in particular, to move into our "Core Concepts with the German Longsword" course).
However, the skills and principles you'll be presented with are intended to be largely "style agnostic," meaning that these skills will serve you well, regardless of whether you are training with San Diego Longsword, another HEMA or historical fencing program, or are moving into a different style of longsword fighting (e.g., the Italian/Fiore tradition).
Good basics are good basics, and can (and should) be applicable across a wide variety of fencing doctrines.
