I have been trading for the better part of 10 years. A year ago I got fed up with sitting all day and got a trek desk (see link bellow) At first I did it about 5 hours a day at a slow 2 mph pace so I could still read and work without any issues. I now only log 5 miles per day on it during the trading day. I would recomend it to any one.

Things to take into consideration:
1)It is good to have a "proper" desk and workstation in addition to the tredmill. There will be times that you want to sit and work.
2)I noticed vision problems when I spend long hours over 2.5 mph.
3) You can build your own if you are inclined to do such things and save a bundle of money. Simply by a treadmill and build a desk that is high enough to sit over the treadmill.
