Biomechanics was a system of actor training developed by Vsevolod Meyerhold. Its purpose was to widen the emotional potential of a theater piece and express thoughts and ideas that could not be easily presented through the naturalistic theater of the period.
The techniques of Biomechanics were developed during the rehearsals of a series of plays directed by Meyerhold in the 1920s and 1930s when Socialist Realism was at its height in Russia. Biomechanics is a precursor to and influence on much of the 20th Century's physical theatre.
