Initiative Description: Nine classroom teachers were provided inexpensive curricula and trained to implement and instruct PA breaks (2 × 30 minute training sessions). The teachers were encouraged to lead 1 activity break per day after the training.

Study Results:Teachers (n = 5) who complied with the recommended 1 activity break per day had students who accrued ∼33% more mean school steps/day at follow-up (∼1100) and post follow-up (∼1350) compared to controls
