Is Exercise Snacks good for cardiovascular health?

The evidence points that way, though it's not yet conclusive. '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. That's reflected in an evidence score of 65/100 for its role in cardiovascular health, drawn from 8 studies (2 RCTs), with an estimated impact on longevity rated substantial (68/100).
