Arrange it so your commute is by public transport. I get through a few books a month without really trying; having a routine where you read a bit every day is how you do large amounts of reading.
The reason given is that it prevents you from accidentally rereading a line or skipping over one or changing lines midsentence.
This seems like one of those gimmicky approaches, and I remember being sold on this approach rather than being entirely convinced. Have you seen this before?
