I. INTRODUCTION
ENTAL imagery is defined as a rehearsal process that
occurs mentally to generate perceptual experience in the
absence of real stimulus [1]. In sport psychology, mental
imagery is a psychological skill used by athletes for
performance enhancement, arousal regulation, affective and
cognitive modification and rehabilitation [2], [3]. However,
sport is just one of the varieties of physical activity that uses
imagery. Another type of physical activity that had been
linked to the use of imagery is exercise. Since imagery had
been proven to be an important intervention in sport for
developing self-efficacy and enhancing performance, it might
also be applicable for exercise behavior [4].
Unlike athlete, imagery used by exercisers is primarily
based on three grounds: energy, appearance and technique [5].
Energy imagery refers psychological images related to boost
of energy and ease of tension; appearance imagery is more to
physical appearance of individual being lean, fit and healthy
