Standing, a simple subject but the more I look into it the more complicated it seems. Four weeks ago I walked into my office and cranked up my disk to a standing position. After sitting for 20 years and often hobbling with a sore back as I stood up I took a leap of faith.Guess what I no longer have a sore back, my core muscles are stronger and I can not imagine going back to sitting all day. One of my co-workers developed a herniated disk and was forced to stand. He is a three time Ironman and in excellent condition yet his back was failing. Tina Dubois had mentioned she no longer sits at a disk. Daniel Lieberman is quoted as saying "we did not evolve to sit in chairs all day". Simple stuff but until you start to think about it just seems normal to sit. Like any new physical activity there is an adaptation period. My lower back muscles are strengthening and often I need to stretch and sit at the end of the day. I talked to the guy with the herniated disk about the transition. He went through the same experience but after about six weeks he stopped having the back fatigue. Until I talked to him about it he had forgot all about his transition. I am lucky to work for a company that supports good ergonomics. A consultant came in and looked at my setup, made adjustments, ordered a foot rest, monitor stands and a key board stand. One of the biggest thing was getting the mouse at the right level so that my wrist was not bent. If I can eliminate things that support and cushion, the stronger I become. PB
