Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to test whether the interventions offering short-term incentives (points redeemable for prizes), specific cued plans, and science-backed tips can help with creating enduring exercise habits. There are four (4) sub-studies within this protocol.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The four sub-studies are:

1. Sweet spot

Past studies have shown that steady routines associated with stable cues are a hallmark of successful habits. However, recent research has demonstrated that incentivizing an overly rigid routine (e.g., every workout must be at the same time each day) creates a less lasting exercise habit than incentivizing a flexible exercise routine (e.g., workouts can be at any time of day). In this study, the investigators examine whether offering higher rewards for exercise that occurs at a planned, routine time than for exercise at other times, but still offering some rewards for exercise outside of these planned moments, may improve over total flexibility for producing lasting habits.
2. Falling off the Wagon (FOTW)

In the long run, missing one workout won't make much difference to a person's overall health. Psychologically, however, missing a workout may lead people to feel they've already failed at meeting their fitness goals, zapping their motivation to exercise in the future. In this study, the investigators examine whether offering 50% larger incentive for exercise to people after they miss a planned workout leads to more sustained exercise habits than incentivizing all workouts equally.
3. Think Twice

Studies have shown that people tend to fall into the planning fallacy -- optimistically overestimating their performance in some future activity. In this study, the investigators examine whether people who the investigators taught about the planning fallacy would make more realistic exercise plans and adhere to those plans better.
4. Weekly vs. Daily Routines (WDR)

This study will examine whether incentivizing people to create a daily routine that is consistent every day for a month or a weekly routine that is consistent every week for a month helps people build a more lasting exercise habit. In the daily routines condition, participants will be required to schedule workouts (and associated text reminders) at the same time of day on every weekday, and the same time of day on each weekend throughout our four week treatment period. In the weekly routines condition, participants will be allowed to schedule workouts (and associated text reminders) at different times on different days of the week, but their schedule must be the same for each of the four weeks of our four week treatment period.

Sweet Spot: Flexible high incentive condition

Participants will receive 500 points if they make a gym visit within a pre-specified window of time and 490 points if they make a gym visit at any other time. 7000 points convert to $25
