Abstract

Lack of exercise and obesity are prominent social problems in the U.S. population. Therefore, understanding the experiences that promote or hinder motivation and exercise adherence is important. A total of 15 adult participants who engaged in CrossFit for a minimum of 6 months were recruited for this generic qualitative study using purposeful sampling methods. They responded to an invitation on a social media page for CrossFit participants. They shared their exercise adherence experiences and motivation through semi-structured qualitative interviews. Trustworthiness procedures included reflexive journaling, and member checking. Data analysis proceeded from transcript reading to working with broad themes and phrases from the text to identify codes, categories and themes related to the research questions. Results of this study revealed that study participants found motivation to adhere from a variety of different sources, including autonomy, pride, and the physical and mental health benefits produced. Use of self-determination theory to guide the analysis revealed that autonomy, connection, and competence were present in CrossFit and support motivation and exercise adherence. Implications of this study suggest future research to better understand exercise adherence and motivation which can positively impact physical and mental health parameters of adults. Application of the results of this study could encourage people better select and better design exercise programs that lend to increasing the likelihood of adherence leading to positive social change.
