The purpose of this study was to explore the impact of an online beginning yoga activity course on college students' well-being, specifically concerning their perceived stress, self-compassion, mindful awareness, and somatic awareness. The research questions were investigated through a quasi-experimental one-group embedded mixed-methods study. There were no significant changes in perceived stress, self-compassion, and mindful awareness after participation in the class. However, two of eight indicators of somatic awareness, attention regulation and self-regulation, changed significantly. Three indicators of somatic awareness -- noticing, body listening, and attention regulation -- emerged as themes in students' weekly logs. The mixed-methods findings indicated correspondence between the quantitative somatic awareness scores and qualitative themes related to somatic awareness concerning attention regulation and body listening. Results suggest participation in an online beginning yoga activity course can impact a college students' well-being; specifically, the somatic awareness indicators of attention regulation and body listening.
