This geekdesk looks like the desk I have. My situation is much like the op. I started really getting back/shoulder/arm pains a few years back, so I started standing up all day. In the beginning it was really hard, but after about one month you sorta get used to it and develop the necessary muscles. Another thing I can recommend is getting one of the good standing mats. Best one I've found is this one: http://www.kybun.com/products-and-stores/kybun-products/kybounder.html http://www.kybun.com/products-and-stores/kybun-products/kybo... They are comfortable standing on, and they make you change positition even more and excersize more different muscles in legs and knees.
