Cash for cardio: do debit card rewards boost gym attendance?
NCT ID NCT05704712
First seen Sep 01, 2026 · Last updated Sep 02, 2026 · Updated 1 time
Summary
Researchers at Brown University are testing whether cash incentives encourage adults to exercise more. Participants with a YMCA membership can earn up to $100 or $200 for attending at least 50 gym sessions over 6 months. The study compares two incentive levels against a control group, tracking gym visits and physical activity over a year. The goal is to see if a simple, insurance-style reward program can meaningfully increase exercise.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Monetary incentives in the form of pre-loaded Visa debit cards, up to $100 or $200 for attending at least 50 YMCA sessions over 6 months
- What this could lead to
- If cash rewards get people moving more, this could point toward a simple, scalable way to boost physical activity and improve public health.
- What could go wrong
- The trial is small and short-term, and the effect may fade once the money stops. Some participants may not change their habits at all.
