Repetition Exercises, originally created by Sanford Meisner, are the most representative exercises in Meisner Acting Training. Through the Repetition Exercises, actors will gradually grasp an acting method based on emotional impulse and instinct, and develop the ability to "actually live in an imagined situation." In terms of developing realistic performance teaching techniques in theory and practice, Repetition Exercises are not only scientific but also important to academic research and practice.
