One-Minute 'Exercise Snacks' could transform daily fitness
NCT ID NCT07718113
First seen Jul 21, 2026 · Last updated Jul 24, 2026 · Updated 3 times
Summary
This study tests whether doing very short bursts of activity—like brisk walking or stair climbing for 1-3 minutes several times a day—can improve physical activity, fitness, and heart health in adults who are not very active. Participants are randomly assigned to either follow this 'exercise snacking' routine for 12 weeks or continue their usual habits. Researchers measure changes in activity levels, body fat, blood pressure, and well-being, and check if any improvements last for another 12 weeks after the program ends.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a behavioral intervention of brief, frequent exercise bouts called exercise snacking
- What this could lead to
- If effective, exercise snacking could offer a practical, time-efficient way for inactive people to improve heart health and fitness.
- What could go wrong
- This is a small, early-stage trial with 60 participants, so results may not apply broadly. Adherence to the snacking regimen may be low, and long-term benefits are uncertain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18-60 years. * Body mass index (BMI) ≥18.5 kg/m². * Insufficiently physically active, defined as generally not meeting current physical activity guidelines for moderate-to-vigorous physical activity. * Able to safely participate in moderate-to-vigorous physical activity as determined by study screening procedures, including completion of the Physical - Activity Readiness Questionnaire (PAR-Q+) and health history review. * Willing and able to provide written informed consent. * Willing to complete all study visits, wear activity monitors, and comply with study procedures. Exclusion Criteria: * 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. * Pregnancy or any other condition judged by the investigators to make participation unsafe or interfere with completion of study procedures.
