The study is designed to compare two methods of delivering short (~10 min) physical activity
breaks that will occur during the regular school day for 3 years. Schools will be randomized
to deliver physical activity breaks led by either the regular classroom teacher or by a
remote instructor through a video in the classroom. Both delivery methods will promote a
variety of whole body movements using large muscle groups. The schools will not be able to
choose which group (regular teacher or remote instructor) they will be part of.
