I think its just bad how it is presented. In elementary school, your only doing literal stretches, not anything to actually help GROW your muscles endurance to things or to burn off calories besides the occasional jog, but you can walk anyways, SO WHAT THE HELL IS THE POINT! And no, you don't get a prize for winning the jog-athon. The only actual exercise is sports, but since a kid so much as touching another student is grounds for expulsion, don't ask how they get away with sports to begin with.
My issue is that this is 0% weight losing regiment, if obesity is the main issue with today's youth besides having no culture, self respect or groundings to grow into a civilized culture.
In MIDDLE school however, your using weights ranging in heavy order, having to use them in rapid succession in order to actually make the grade. This happened in my middle school, I had gym, FIRST class, of every day, all year, and I had to lift a 50 pound weight, every day, 10 times, in 10 different machines, within an hours time span, first, I would be more or less tired from sleeping all night, then I would have to fight that and extremely short-shorts that I SWEAR if they popped they would take my underwear with it and everyone in the class gets to see my nad and daddie-os for that day. Finally, I'd also have to fight cramps and other things that could cause that bar to slam around my neck like a very heavy necklace.
Do you see the issue here? There is 0 workout to even get sweaty when your in the Elementary School, but in the Middle school, your having to instantly lift heavy object ranging unmanageable levels. I think that I had to go home for the day in Middle School over having a sprain in my left arm from the weights, along with the inevitable scrathes, sometimes cuts and a very hurt thumb on my right hand.
