I think this is a bad idea. Even if the weights are private kids will speculate and tease. That is kids. Why don't they instead give all schools their hours of gym back and clean up the awful school lunch menu. The school lunch menus today are all fast food and starch. Get rid of the soda and junk food machines. Get rid of the candy in the school store. Ban the use of personal video games at recess.
Just my opinion.
