This is one of the core solo drills we use. It incorporates all of the major blows of the sword in Fiore's system, in several forms, and almost all of the guard positions. The video shows the whole drill, but only part one is required at Level One.

The second half can be easily trained as a circular drill, with the last blow of the drill (the thrust in bicorno) as the feed for the first (breaking the thrust from fenestra). This is shown below:
