Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Participants will be randomized to one of two groups.
Primary purpose: PREVENTION

Brief summary: The purpose of this study is to evaluate the efficacy of three, brief (10-minute) theory-guided video chats for increasing self-efficacy for lifestyle physical activity versus a time-matched video chat comparison group designed to increase self-efficacy for work-life balance. Participants will include individuals who are low-active, full-time (\>35 hours/week) working adults.

Detailed description: Eligible participants will complete three brief (10-minute) video chats to promote self-efficacy during the first three weeks of engaging in lifestyle physical activity. Randomization will place participants into one of two groups: (1) Social Cognitive Theory-guided video chat or (2) time-matched video chat comparison group. Video chats will be delivered via the Google Duo smartphone app.

Baseline and follow-up assessments will consist of psycho-social questionnaires assessing constructs of the Social Cognitive Theory, affect, stress, and work-life balance. Physiological measures including heart rate will be assessed during a baseline treadmill assessment (to be completed in lab). All participants, regardless of group, will be asked to wear an activity tracker for the entirety of the study for assessing lifestyle physical activity. The comparison group will be asked to complete all baseline and follow-up assessments but will not receive information relative to lifestyle physical activity. The baseline assessments will take place with an academic research laboratory and weeks 2-7 will take place off outside of the lab.

Eligibility criteria: Inclusion Criteria:

* 25-64 years of age
* inactive (defined as not participating in exercise for 2 or more days per week for \>30 minutes over the past 3-months)
* willing to be randomized to any condition
* owns iOs or Android smartphone

Exclusion Criteria:

* unable to speak or read English
* having a cognitive impairment (assessed via modified Telephone Interview for Cognitive Status \[TICS\]; score less than 21 will result in study exclusion)
* unable to exercise at moderate intensity level without causing or exacerbating a pre-existing condition which prevents participation in an exercise program
