Tracking. Participation in the videos for all groups (LD, MD, STC) will be tracked (class taken, time of day, length of use etc.) on the Udaya.com website throughout the study. Before beginning the study, the research team will send each participant a daily log Qualtrics link to self-track: (a) completion of yoga/stretching sessions; (b) rate of perceived exertion; (c) assessment of mindfulness; (d) other PA participation; (e) participation in psychotherapy (i.e., cognitive behavioral therapy); and (f) pregnancy, mental health, and use of psychiatric medication (see daily/weekly log). Research personnel will contact participants weekly (via email/text) to remind them to participate in yoga/stretching and complete daily/weekly logs. Participants will be given a choice of text or email reminders. If a participant from the intervention or STC is not meeting their minimal dose requirement and/or not tracking their sessions, research personnel will reach out to the participant via text/email reminder.
