Stanislavski further elaborated his system with a more physically grounded rehearsal process that came to be known as the "Method of Physical Action". The term itself was only applied to this rehearsal process after Stanislavski's death. Benedetti indicates that though Stanislavski had developed it since 1916, he first explored it practically in the early 1930s. The roots of the Method of Physical Action stretch back to Stanislavski's earliest work as a director (in which he focused consistently on a play's action) and the techniques he explored with Vsevolod Meyerhold and later with the First Studio of the MAT before the First World War (such as the experiments with improvisation and the practice of anatomising scripts in terms of bits and tasks).
