I'd like to address your question not specifically about jogging in place (which would be a fine way to burn some calories while watching TV for instance). But your idea of jogging made me think of some recent work out of the Mayo Clinic concerning various ways that one can increase calorie burning throughout the day. Some would refer to these activities as "fidgeting", but here is an example: while standing in the kitchen fixing dinner, do some knee raises; while watching TV, get up during the commercials and walk around; park your car farther away from the grocery store; do some arm lifts while working at your computer (include a 3-lb weight); walk to give someone a message in your place of work instead of sending an email, and on and on. Sounds silly, but people who "move" more without really thinking about it, burn 400-500 more calories than those that don't. So if you are watching TV, jog!
