Gym class at my school is often anything but physical activity.
The gym teacher for 5th grade this week - for the once-a-week gym class - made the students write a legal document promising to behave. While crouched on the floor, writing on the hardwood. This left only 10 minutes out of the hour for exercise. The gym teacher then introduced a game of line tag with a rule: no running! Only walking!
Last we checked, minors can't be party to a legal document. And this state has one of the highest obesity rates in the US.
