Brief Summary
The objective of this study is to optimize a novel, audio-recorded physical activity intervention that is scalable. Using principles of the Multiphase Optimization Strategy (MOST) framework, a full factorial study will test the unique and combined effects of different intervention components to identify which combination of components is optimal for increasing physical activity and mechanisms by which the components are or are not effective. This information will inform decisions about an optimal intervention package that is effective, efficient, and minimizes participant burden.

Outcome Measures
Primary Outcomes (1)
Change in Weekly Physical Activity Minutes Across 6 Weeks (accelerometer-assessed)
Amount of weekly moderate-to-vigorous (MVPA) minutes (i.e., minutes of MPVA weighted by intensity) will be determined from accelerometers (ActiGraph wGT3X-BT) worn for one-week periods for six consecutive weeks.
Assessed weekly at Weeks 1-6
Secondary Outcomes (1)
Change in Weekly Physical Activity Minutes Across 6 Weeks (self-reported)
Assessed weekly at baseline and at Weeks 1-6
Other Outcomes (5)
Affective Response to Exercise
Assessed weekly at baseline and at Weeks 1-6
Intrinsic Motivation for Exercise
Assessed weekly at baseline and at Weeks 1-6
Delayed Discounting
Assessed weekly at baseline and at Weeks 1-6

Interventions
Participants will listen to a guided thinking task directing them to think about themselves at a future, positive event and to imagine the event in vivid and specific detail.
Participants will listen to a guided thinking task directing them to think about positive feelings and associations about physical activity in specific, personal, and positive detail.
Participants will listen to a guided thinking task directing them to think about the remainder of their week and when, where, and how they plan to attain their remaining activity for the week.
Participants will listen to the audio-recording with the guided thinking tasks 5 times/week.
Participants will listen to a guided thinking task directing them to think about a regular habit or activity they completed in the past week and to imagine that activity in specific and vivid detail.
Participants will listen to a guided thinking task directing them to imagine physical sensations (i.e., movements, muscles used) of a routine, daily activity (non-physical activity).
Participants will listen to the audio-recording with the guided thinking tasks 1 time/week.
