Marozzo provides a progression that may be used to practice the various guards and some attacks.  The following is a list of the progressions and how to move from one to the next.  Note, that in the illustrations not only are bucklers used but also capes and daggers as well as the single sword alone.
 

Guardia di Coda Lunga E Stretta

Start in this guard with the buckler held out in front of the body with the arm extended.  Attack with a mandritta squalenbratto and pass the left foot forward.


Cinghiara Porta di Ferro Stretta

In this guard the buckler should be close to the body and high.  Attack with a falso manco and pass the right foot forward.

Guardia Alta

The buckler should be out in front of the body with the arm extended.  Pass the left foot forward and cut downwards with the sword.
