Can a 15-minute "concentrated walk" a day extend your lifespan? Instead of breaking it up, "concentrate" it. Here's why a 15-minute walk boosts health benefits.

A recent study analyzing large-scale data from the UK Biobank, published in the Annals of Internal Medicine in October 2025, has shown that continuous walking sessions of 10-15 minutes or more are more strongly associated with a reduction in cardiovascular disease and mortality risk than accumulating short, intermittent walks, even when the total daily step count is similar. The effect is particularly significant among those who typically do not exercise and take fewer than 8,000 steps a day. On social media, practical suggestions such as "replace your morning commute with a 15-minute walk" are spreading, while there are also cautious remarks pointing out that "causality is not confirmed in observational studies." The conclusion is simple: "On days when you can, aim for a continuous 15-minute walk," as this walking style seeks to achieve the maximum effect with minimal investment.
