In social cognitive theory, reinforcements can be internal factors such as personal reward or external factors. For me, my reinforcement has come in the form of motivation and support from my friends and the feeling of accomplishment every time I complete a workout class. When I committed to participating in group fitness classes, I was lucky enough to convince a few of my friends to join us as well and together we became a mutual support system. They push me to attend classes and the reinforcement of the feeling of total completion after a given class motivates me and pushes me further to continue my positive growth. For any change to be successful, we must always push ourselves, because when you change your lifestyle, such as becoming more physically active and joining a fitness group, we must always continue to work and create new goals, because we are changing and we are constantly progressing.
