Generally those workers are also moving around, not standing absolutely still with their arms held out in front of them. Standing desks don't insulate you from the need for frequent breaks.
If you're standing absolutely still at your standing desk, you're kind of crazy. I'm constantly moving; right now I'm sort of idly shifting back and forth from left foot to right. And my arms aren't held out in front of me, they're at my sides and bent loosely at the elbow to reach my keyboard and mouse. When I'm not typing and just thinking a bit, I stick my hands in my pockets, too--I don't leave them sitting on the desk.)
I think it's just making me turn against blogging rather than Medium in particular. It's as if the world collectively decided in January of 2015 to start every article with "Why I took a bath" or "How standing became sitting". Not every little thing in the universe needs an article written about it. But I'm a hypocrite, I just read that entire post and now I have sour grapes about it. That's more of a lesson for me about wasting my time more than anything.
Yeah. I've been standing about 8 hours every day for over a year now, taking short breaks on a "saddle seat". I dread sitting in an office chair now. I also do weighted squats regularly which probably helps. It takes a long time to adjust, but it was worth it.
I've been meaning to try out a balance board for some extra variation too - something like FluidStance or Wurf Board.
Nope. I think the one I'm thinking of had a green website with a photo of a MacBook and a grey tablety thing that detected your hands. This was long before Leap was a thing.
I think the tablety-thing was an L shaped touchpad, where the depth sensors were in the | part of the L.
Guy can't stand up for more than 4 hours, writes complaints on Medium. Articles like this are why the tech industry gets a bad name.
