Here is some study stating that gym classes don't really matter all that much when it comes to childhood obesity.
Personally, I think that what matters is what the parent teach the children at home, and by extension, close family members. For example, it is very normal to exercise in my family. Both of my parents make the time, my brother and sister-in-law do as well, and my niece and nephew understand that mommy needs to go for a run, Aunt Tine has to go to the gym or that Papa is at his yoga class (yes, my dad is really into Bikram Yoga, don't mock... I suspect he does it for the eye candy).
We need to stop expecting the schools to do the parent's job.
Side rant.... I read an article the other day about how even people in normal weight ranges "diet"... and the article made it sound like a bad thing. Well, maybe they stay in the "normal" range because they watch what they eat!
Another side rant... will it ever stop raining?! I'm so sick of this shit. I want to wear dresses and skirts and not be bundled up like a fucking waterlogged Eskimo.
