When I managed a team, I tried to encourage my team members to take walks during the day. I've always found they help me get to a more reflective mindset as well as the movement and sunlight getting me back to a state where I can focus. But, more importantly, I wanted to avoid a culture where people felt like they needed "ass in chair" time to prove they'd worked. If everyone saw everyone else getting up and going elsewhere multiple times per day, they'd feel comfortable doing the same. It worked, in some sense...we got more done than most teams. But on an organization-wide basis, we got a bit of a reputation in other teams of being absent a lot which I constantly had to push back against during callibrations when deciding raises and promotions.

Overall, it was both encouraging, since I'm now convinced that humans work better in short bursts followed by at least some physical activity, but also discouraging in the organizational friction I encountered in my experiment.
