My No-Excuse Workout Machine

How’s this for serendipity: I just discovered that the elliptical machine which we bought used for a ridiculously good price can hold this beat up old Thinkpad on its console. The smaller set of handles, keeping it snugly in place, also serve as perfectly-placed hand rests for typing. For an internet addict who works from home, it’s my perfect no-excuse workout machine.

What sort of things do you guys use to keep yourself occupied while slogging through the monotony of aerobic exercise?
