What this study is
Regular physical activity is associated with numerous health benefits, yet many young adults do not achieve recommended levels of physical activity. Exercise snacking, which involves performing brief bouts of physical activity throughout the day, may provide a practical alternative to traditional exercise programs by making physical activity easier to incorporate into daily routines.
This randomized controlled trial will evaluate whether a 12-week exercise snacking intervention improves physical activity levels, aerobic fitness, cardiometabolic health, and psychological well-being in insufficiently active young adults. Participants will be randomly assigned to either an exercise snacking intervention or a usual behavior control group. Assessments will be completed at baseline, after the 12-week intervention, and after an additional 12-week follow-up period to determine whether any changes are maintained after the intervention ends.
The study will measure physical activity using wearable activity monitors and assess aerobic fitness, body composition, blood pressure, blood lipids, glucose, exercise motivation, affective responses to exercise, and mental well-being. The findings will help determine whether exercise snacking is an effective and sustainable strategy for improving health in young adults and may inform future physical activity recommendations and interventions
What's being tested
- Exercise Snacking
Intervention · BEHAVIORAL
Participants assigned to the intervention group will complete multiple brief bouts of moderate-to-vigorous physical activity throughout each day for 12 weeks. Each exercise snack will typically last approximately 1-3 minutes and may include activities such as stair climbing, brisk walking, repeated sit-to-stands, body-weight squats, or other moderate-to-vigorous activities that can be incorporated into daily routines. Participants will receive standardized written instructions, examples of exercise snacks, and periodic follow-up visits to monitor adherence and reinforce study procedures.

You can't join if
- Known cardiovascular, pulmonary, metabolic, neurological, orthopedic, or other medical conditions that would make participation in moderate-to-vigorous physical activity unsafe.
- Resting heart rate >100 beats/minute at screening.
- Resting blood pressure >160/100 mmHg at screening.
- Clinically significant electrocardiogram (ECG) abnormalities identified during screening that require medical evaluation.
- Current participation in regular structured physical activity that meets or exceeds recommended physical activity guidelines.
- Physical limitations or injuries that preclude safe participation in the intervention or fitness testing.
- Moderate-to-severe psychological distress or other mental health concerns identified during screening that require referral or would make study participation inappropriate.
