I know. It sounds like the usual gimmick: Get fit while you watch TV.
Below are a few exercises that even the most housebound person can perform with a little effort and dedication. So tune in to your favorite show, and by the time you hear Frank utter, "Holy crap!" or you discover who wins "Cupcake Wars" (ah, better skip that one), you might be well on your way to fitness.
Complete the recommended number of repetitions for each move and immediately move on to the next. After you've completed all the exercises, rest for one minute and then repeat the entire circuit one to two more times. If you haven't been off the couch in a while, start slow and work up to the suggested number of repetitions/circuits. Do these at least three times a week.
