I'm actually about to shift my workflow in a major way to include more movement. Already use an adjustable desk, standing in the morning and sitting in the evening. And when I'm on calls, I always use a headset and walk-n-talk.
This is very far from exercise but it might feel to you as exercise and an increase of movement because your perspective on the physical abilities of the average human is skewed. One astonishing thing I've learned while becoming more active is what a normal body is really capable of without going into the realm of professional athletes. Running a marathon with a slow pace is really feasible. So is lugging a 15-20kg backpack for 35-40km per day for about a month or rock climbing/bouldering in the lower difficulties. To achieve either of it you wont need a very hard exercise regimen either, rather persistence.
Please don't take this as personal criticism. I just find it important to point out that there is a huge gap between what people unfamiliar with sport perceive as achievements and what actually are achievements. Just put in 4 hours of running and 4 hours of climbing per week and you will see for yourself.
Edit: Or I just failed to see the sarcasm in your post. Entirely possible :)
See my comment above. I've actually been an entrepreneur, teacher, trainer and comptetitor in the health and fitness field for the better part of the last 15 years. But the last few have seen a lot more screen time, so I'm doing what I can to change that.
He just said that he intends to include more movement in his daily routine [0]... nowhere did he say that it was exercise, or sport, or a physical feat.
Seriously. Why do all of you born-again iron men have to come out of the wood-works as soon as people start sharing (not even bragging) their incremental efforts (you said it yourself: persistence) to lead healthier lives? We get it: you are better than them when it comes to fitness (well, the grandparent could be a former Olympian, for all we know. Or he might be an amateur sportsman who also has a sedentary job). Please stop one-upping people that are just getting off their feet when it comes to this.
[0] The importance of which seems to be distinct from exercising regularly, at least if you don't have time to exercise for hours on end each day:
Completely agree, as I do with the comments below. A wide range of "real" exercise, from high-intensity training to endurance and flexibility, has and will continue to be a part of my life.
My comment was just on the narrower idea of making the insane number of hours I (and most people) spend in front of a screen or on calls every day a whole lot less sedentary.
