"Recent research finds that the act of walking leads to increases in creative thinking. This certainly supports the usefulness of walking meetings. Plenty of anecdotal evidence also suggests that walking meetings lead to more honest exchanges with employees and are more productive than traditional sit-down meetings."
"Those who participate in walking meetings are 5.25% more likely to report being creative at their jobs than those who do not.

Those who participate in walking meetings are 8.5% more likely to report high levels of engagement."
