Standing is an easy small change that you can make starting right now. Standing up when everyone else is sitting can be a mark of pride in your office. I know this because I did it. I build myself a standing desk for only about 30 dollars worth of Ikea parts. I had been sitting for over a year and it was not doing my body any good. I realized that standing would be healthier option than sitting myself to death.
It all started when my lower back began to hurt. I tried everything to help get it back to normal.
