I have tried that but i like to be stationery..Just by standing up you increase your metabolic rate to help burn fat. I find about 20-30 minutes at a time is all i can handle(unless i so focused i actually forget i am standing up,lol which does happen,) then i will sit again. But as long as your not sitting for more than 30-60 minutes at a time then it is good...but the main thing is the posture, i was getting issues with not only my back but one of my legs was starting to weird out as well, so it was a matter of having to find a solution . All i know is that since i made changes my productivity is 10x better.
