I don't sit except when necessary. I can do that because I'm looking for a job. It's been a few months and I noticed my bad back condition drastically improved out of sudden. I promised myself to never sit again in front of computer at home. I Currently have my PC next to bed. Standing desk is not a solution. Standing for long periods is less healthy than walking. Ask any barber about occupational diseases. They'll tell you there are issues with knees and blood circulation. Ask any person whose job involves standing for long periods of time, like a shop clerk. I do 40 minutes of core exercises 4 times a week due to my bad back, and it's helping a great deal. Recently I started incorporating the ultimate back exercise - pullups. But I believe the long term solution is a chaise or a very horizontal recliner, like a dentist's chair. Obviously you're NOT going to get something like that installed at a typical job unless you're the CEO I guess.
