Exercise psychology is defined as the study of psychological factors underlying participation and adherence in physical activity programs (Anshel, 1948). Health and exercise psychology have gained much prominence over the last few decades especially when it comes to explaining and understanding exercise behaviours (Berger, Pargman, & Weinberg, 2007).The advancement of technology has made life easier resulting in more physically inactivity both at work and in our leisure-time (Engstrom, 2010). Therefore, there is still significantly high prevalence of overweight and obesity (Ku et al., 2006; Niñerola et al., 2006), both in childhood and adolescence (Trost and Loprinzi, 2008).Chronic disease and obesity have received most of the attention in public health (Williams, P25). Obesity is the second highest cause of preventable disability and death in the developed world (House of Commons Health Committee, 2004). Exercising regularly is highly beneficial for health and psychological well-being (Biddle, 1993). Although there is large number of research on the beneficial influences of exercise on psychological and physiological well-being, studies and research have found that only about small percentage of children and adult population participates in physical activity (The National Public Health Report, 2009). Anshel (2006) found the commonest motives to perform exercise were weight management and improved health. whereas, much research has stated the barrier to participation in exercise is a' perceived lack of tim'e (Gómez-López, Granero Gallegos & Baerna Extremera, 2010; Lovell, Ansari & Parker, 2010; Tergerson & King, 2002).There are psychology theories that have been applied to the exercise setting in an attempt to explain why people don’t exercise, why they start to exercise, why do they stop. These theories include (a) the theory of reasoned action, (b) the theory of planned behaviour, (c) the
