We recently bought a recumbent bike, set it up in our living room, and POOF! We use it! It’s easy to talk yourself into sitting on a bike and pedaling while watching TV. It doesn’t take up much room, but must be in front of the TV if that is where you spend your time. Reading is also a great way to pass your time biking!
I no longer feel bad for watching TV (although, I really don’t watch much TV), because I can workout while watching my favorite shows, Biggest Loser and House Hunters International.
So spend just a little – you can get a nice bike for about $125 – and watch TV (almost) guilt-free.
