Problem is, this is one organized activity that probably should be a requirement. When faced with the election to be active and in shape in their non-school lives, many kids are already electing out. I expect much the same decision will be made for in-school programs. If not in school, where will most kids ever be exposed to organized fitness and sports programs?
I suppose gym could be a good option, but most of the gym teachers I had in school sucked. I hated gym with a passion. Course, I hated all of my high school with a passion.
