It's proof that it worked for me. Somebody of average genetics and physique that had a lot of the same problems that others complain about and in turn try standing desks. Sometimes it's best to just give it a shot and see how it works for you instead of trying to find reasons not to try it. :)
Make that n of 2: I began exercising everyday about 1 1/2 years ago, after over 15 years of zero exercise. Didn't change my diet, nothing besides the exercise which was basically an hour of basketball nearly everyday. Arms, legs, back, stomach, shoulders, neck, hands, fingers and toes are all getting toned, with the occasional muscle bulging a bit, and better yet - dropped 20 points of cholestrol and 10 points of sugar, among other gains. Feeling great too, with a lot of stamina. I'm once again enjoying the pleasure of being able to continue running and playing even while getting winded, instead of feeling like dying after the first 30 yards.
