Seconded, although I recommend something much more simple: a standing desk. I stand when I get uncomfortable sitting, I sit when I get uncomfortable standing. And if I start to space out I can go for a walk or run. I'm very lucky to have this convenience.
You don't need a super-expensive desk either, in fact you probably don't need to buy anything. I use the counter-top at my house, you can also get a box or chair to put on your regular desk.
