Some people have advanced radical solutions to the sitting syndrome: replace your sit-down desk with a stand-up desk, and equip this with a slow treadmill so that you walk while you work.

Capture these thoughts with a hand-held micro-cassette tape recorder. Dictate memos, grocery lists, research papers or the Great American Novel while you walk.

Since running and walking speeds differ from species to species, the speed at which the treadmill moved was varied so that it raised the heart rates of the different participants to the same level.
