I have a gravel floor which helps standing long periods I also have a stool to lean on, I have no need to stretch cause it's seems I drop something every min or so or my stray cat collection knocks stuff off, so I'm bending all the time. I started squatting down and I work out 3 to 5 times a week with weights. I don't do cardiovascular and I should, but I am going to get a bike and start riding.
You have to just put in the effort. I have a tv in the shop with local channels so if I need to watch TV I can do so then, the tv was a scrap pickup and has some small lines on it but it works.
