Grab a sofa, park yourself, watch your favorite TV show and get some exercise done with the Sofa Bound workout. As a matter of fact there should be no TV show you should watch without doing the Sofa Bound workout. It's a Level V workout because of the intensity of the load it applies to skeletal muscles, however the rep count is low as it is time-based which means you can integrate it into your day to day TV-watching without any difficulty. You'd be surprised at the difference this makes to your overall fitness level.
