Just one minute of hard cycling a week might improve your health

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether doing a very short, intense cycling workout just once a week can improve aerobic fitness as much as doing it twice a week. The workout, called REHIT, involves only 10 minutes of easy cycling with two 20-second all-out sprints. The study aimed to see if one session per week is enough to boost fitness in healthy but inactive adults. However, the study was terminated early and only enrolled 15 people, so the findings are limited.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Reduced-exertion high-intensity interval training (REHIT) - a 10-minute cycling workout with two 20-second all-out sprints
What this could lead to
If it works, this could show that even one short weekly workout improves fitness, making exercise more accessible for busy people.
What could go wrong
This is a very small, terminated study with only 15 participants, so results may not be reliable or apply to the general population.
