In US schools most students are forced to exercise about 30 minutes per day during gym class. I had this from at least 6th-10th grade, though maybe only a handful of days per week had any serious exercise, usually running or playing sports like soccer or basketball.
Not in any schools I attended or have had children in. You got gym maybe 1 to 2 times a week. In elementary school you were expected to run around during recess. In middle school and high school we had a proper gym class 3 days a week.
