These various exercises include the 'physical tension and relaxation' exercises that would help them relieve from the physical stress they carry while performing and help them present their roles more effectively while 'simple movement' exercises would aid them to perform the actions constructively and smoothly on stage and the 'vocal exercises' would assist them in delivering their dialogues fluently and efficiently.
