Does Exercise Snacks actually make a difference, or is it overhyped?

'Exercise snacks' are very brief, often under a minute, vigorous bouts of activity woven into daily life, such as a fast flight of stairs or a brisk uphill walk, made measurable by wrist-worn accelerometers that can detect movement patterns self-report cannot capture. Weighing the data: Exercise Snacks looks potentially significant but still under-researched — its estimated impact on longevity is rated high (68/100), while the evidence itself is only moderate (65/100).
