Not to argue one side or the other but a lot of posters keep mentioning "what if the kid doesn't want to exercise/do activities/etc?" Yeah well kids make bad decisions, a lot of bad decisions. As an adult it's your job to make better decisions for them. Imagine if we let kids do whatever they wanted whenever they wanted? Not a good plan. My parents always forced me to do extra curricular activities and sports. My parents never allowed me to eat lunchables even though they were soooo popular and I wanted one soooo bad. And you know what? As an adult I realize they made the right decisions for me. I'm a better, healthier person now because of it. Children are simply not aware enough to make their own decisions which is why we have parents!
