While I see your point (0 > 1, by definition) I think this sends the wrong message.

You need several hours of relatively strenuous exercise per week. Walking around the neighborhood, or your house, or whatever has diminishing returns. You need to steadily increase load to continue to see results. The body is incredibly good at adapting. People will read your statement and walk around their house twice, sit down, and not move for the rest of the night.
