Unfortunately management thinks that lines of code written or token usage or seats in butts or {insert random quantitative metric} equals peak productivity.
I have never been at my best rock climbing performance without a substantial amount of walking; even if I am training well, eating well, sleeping well, climbing with others, and super enthusiastic, the element of walking is for some reason critical.
My suspicion is that the human body is designed for walking (eg, we are upright, our shoulders adapted to swing the arm) and that myriad processes simply will not occur or will not occur optimally without walking. I believe restoration on a cellular level is enhanced by walking, that various cognitive and sub-cognitive processes are aided by walking, and that many of these processes sync up with a sort of supermodular (https://en.wikipedia.org/wiki/Supermodular_function) effect when walking.
Small training sessions at work, throughout the day, are also great to build a strong team spirit and feel pumped all day. Unfortunately, people tend to rigidly compartmentalize rather than seamlessly integrate physical activity into their lifestyles.
So it's good for strength too!
It's good to hear that there are gym trainers who advocate for this. From what I've seen, this approach seems to go contrary to popular belief and some people tend to be quite adamant about it, insisting on specific routines, splits, and rest days, but it's how I went from not being able to do a single push-up to effortlessly doing 10 consecutive one-arm push-ups. I just practice.
