Allow each child to select only one or two favourite TV programs. For every hour they watch, get a commitment for equal time engaged in physical activity. Make the same guidelines for yourself as well.
Find out who can do the most jumping jacks during the commercial breaks.
Run on the spot, try push-ups and sit-ups, and stretch during the commercials of your favourite television show.
Take out a fitness program video when you rent an entertainment video. Do the fitness video together before settling in for the other one.
Make a game out of it - Challenge yourselves to do as many push ups (i.e. using the wall, going from your knees, or from your toes) as you can during one commercial. For the next commercial, challenge yourselves to do as many crunches (i.e. shoulder blades off the floor, hands up to knees)
During the commercial break, walk up and down the stairs 3 times before returning back to the TV.
