How effective at improving flexibility/posture/fitness/general health is using a standing desk instead of a sitting desk?
A recent meta-analysis of 23 published studies is MacEwen, MacDonald, and Burr, "A systematic review of standing and treadmill desks in the workplace," Preventative Medicine 70(January 2015):50-58.

Quoting from the paper's summary:
Treadmill desks led to the greatest improvement in physiological outcomes including postprandial glucose, HDL cholesterol, and anthropometrics, while standing desk use was associated with few physiological changes. Standing and treadmill desks both showed mixed results for improving psychological well-being with little impact on work performance.
At a first glimpse the standing desks seem like another "improvement" companies throw to an item to make customers upgrade and re-buy the same thing. Essentially it's just a desk, right? That's what I thought until I started my current job which provided me with a standing desk.
My job is sedentary and very static. I experimented and on some days remained sitting without raising the desk for the whole day. As a result my lower back would start hurting a little(old injury) and my legs would start feeling bloated. I would have to go for a long walk afterwards to get rid of this uncomfortable sensations.
Currently I spend the first hour at work standing, having my desk raised. Then I sit down and switch every hour or so. I would work standing until I get tired. I cannot really say that it gets my blood going but it provides me with a chance to change my posture to something more natural than sitting.
If you do a quick research you will find out that a lot of the back problems are developed by office jobs. By sitting on a chair for hours. Like for example - Discopathy, Disc Hernia and so on and so forth. Standing tall, straightens your back and allows you to avoid this.
I am personally about to buy a standing desk for home too. It's a game changer for me.
According to Dr. Jos Verbeek of The Finnish Institute of Occupational Health, "What we actually found is that most of it is, very much, just fashionable and not proven good for your health."
Anecdotal, I've been using a standing desk for about a year. I write software so it used to be ~8hrs sitting. Now I'm always standing.
Dont notice a difference tbh. Some days my legs and lower back are sore if I happened to walk to work that day. If anything, now when I sit for a long time my lower back feels some soreness on getting up.
Being immobile in one position (whether sitting or standing) for long periods of time is just not good for you.
Sit too long and you get all those posture problems and what not.
Stand too long and blood pools to your calves.
The natural state of man is to go between periods of rest and motion. Either you are laying around loafing or MOVING (walking, running, building).
It is NOT the natural state of man to be immobile in one position for 4-8hrs at a time.
