This Drabble strip speaks to me. (Edited to fix link.)
The issue with exercise for me isn't physical exertion; it's time. I'll grant that the net gain is likely to be higher than depicted here. That doesn't motivate me; I find my actual time now more valuable than my hypothetical time at the age of 90.

I haven't used a stationary bike (only the transportation-oriented ones); do you need to hold on to the handlebars (a) at all and (b) more than trivially? (I don't see well enough to be able to just plop the reading material down on top of the bars, so at least one hand has to be dedicated to holding it up and the other has to be available for page turns.)

We used to put the home exercycle in front of the TV, but that didn't work as well.
