Physical activity (PA) has been pervasively acknowledged to be a significant variable in terms of prevention and treatment of numerous health problems and improving cognitive functions and quality of life (Regardless of PA’s health benefits and the stipulation of public recommendations for PA levels, PA levels remain low among healthy adult people with a percentage of 31% of adults are physically inactive (Contributing factors to low performing of and adherence to PA which are consistently reported in the literature include individual characteristics—for example motivation and self-efficacy—perceived barriers to PA, for instance time and access, in addition to the characteristics of PA behavior, such as PA type, intensity and duration (International health policy has emphasized the significance of the workplace as an effective environment for encouraging employers in terms of promoting their health and well-being (Individualized consultation offers efficacy in terms of strengthening people’s PA levels, comprising of elements that aim to enhance PA in accordance with individuals’ specific needs (Previous interventions that aimed to alter behavior towards healthy lifestyles, such as physical activity, weight reduction and healthy dietary patterns, have showed efficacy of behavioral change strategies in changing behavior. These techniques include goal setting self-monitoring and regular feedback (Goal setting is a self-regulation skill encouraging individuals to establish specific behavioral change objectives that fulfil their requirements. It involves details pertaining to individuals’ planning, for example definition of a specific behavior, frequency, intensity or duration, as well as determining context (where, when, how, or with whom they perform the behavior) (Healthy behavior interventions that include increasing physical activity and improving healthy diet must aim to motivate people’s regular engagement in physical activity. Furthermore, it is necessary to enhance people’s access to physical activity programs, which may be successfully implemented via telecommunications, including telephone consultation, mobile phone text messaging and social media.Significantly, web-based interventions have been developed and evaluated for delivering PA programs. These offer certain advantages over printed materials, face-to-face and telephone contact, for example their accessibility to a significant number of people at low cost, as well as their availability 24 h a day for providing instant and tailored feedback (Changing behavior has been emphasized by Social Cognitive Theory (SCT) which is considered as one of the most predominant theoretical approaches in PA interventions because it provides a framework for understanding and improving PA (
