Great advice, Grant. I'm much like you. I exercise (at home - gym membership at the moment isn't possible) 3 times a week. I am allowed only 2, 15-minute breaks per day - once in the morning and once in the afternoon. I set a timer using Windows 10 Alarm & Clock app, to stop once an hour. I'll get away from my PC and walk outside for a minute, using the stairs going down and up (I work on the third floor). I walk during my lunch, so have to eat at my PC (I'm an hourly employee, so watching the clock is paramount). I average over 10K steps per day with this regiment. Yeah, I'm still overweight, but I know I would be a lot worse, if I didn't do this.
Concerning helping with stress is why I do this, as well as trying to be as healthy as I can be. And let's be honest, as much as you can manage stress there are certain stressful situations/environments/what-have-you we all deal with which we cannot control or remove. So, I do my regiment to help me deal with it, at least better than not doing my physical regiment.
