Brief Summary
This study will evaluate adherence to four types of walking programs. Participants will be randomized to walking programs that included either (1) affect-based exercise intensity, (2) self-selected (or "choice-based") exercise intensity, (3) heart-rate based exercise intensity, or (4) heart-rate guided exercise intensity with the emphasis on affective benefits.

Outcome Measures
Primary Outcomes (1)
Change in objectively measured exercise behavior
Minutes per week of objectively measured exercise behavior.
This will be measured throughout the baseline assessment period (2 weeks) and intervention period (4 weeks)
Secondary Outcomes (6)
Change in self-reported exercise behavior
This will be measured throughout the baseline assessment period (2 weeks) and intervention period (4 weeks)
Change in affective attitudes
Measured during baseline assessment period and at the end of the intervention
Self-reported intrinsic motivation (questionnaires)
Two weeks into study intervention
Enjoyment
Measured at the end of the intervention period (4 weeks)
Change in weight
Measured at the beginning and end of the study (6 weeks).

Choice-No Affect
EXPERIMENTALThese participants self-select (i.e., choose) their exercise intensity with the goal of walking 30-60 minutes on most days of the week. For safety reasons, they are instructed not to exceed 59% of their heart rate reserve. This is choice-based exercise intensity with no focus on positive affect.
Choice-Affect
EXPERIMENTALThese participants self-select their exercise intensity with the goal of walking 30-60 minutes on most days of the week. They're instructed to choose the intensity that makes them feel the best. For safety reasons, they are instructed not to exceed 59% of their heart rate reserve. This is choice-based exercise intensity with a focus on positive affect.
No Choice-Affect
EXPERIMENTALThese participants regulate their exercise intensity using their heart rate, with the goal of walking 30-60 minutes on most days of the week. The intensity is "moderate" according to the American College of Sports Medicine (40-59% of their heart rate reserve). Meanwhile, these participants are instructed to focus on the "good feelings" that come with exercise. this is heart rate-based exercise intensity with a focus on positive affect.
No Choice-No Affect
ACTIVE COMPARATORThese participants regulate their exercise intensity using their heart rate, with the goal of walking 30-60 minutes on most days of the week. The intensity is "moderate" according to the American College of Sports Medicine (40-59% of their heart rate reserve). This is heart rate-based exercise intensity with no focus on positive affect.
Interventions
Participants are instructed to choose whichever intensity they want, rather than regulate their intensity based on heart rate.
Participants are instructed to focus on feeling good while exercising.
Participants are instructed to regulate their exercise intensity based on their heart rate.
