Objective: We evaluated the feasibility of Pitt Moves, a classroom-based, peer-led physical activity break (PAB) intervention developed by graduate students to improve mood, focus, and boredom among students. Participants: One hundred and thirty-two graduate-level students in 10 courses during an academic semester. Methods: Process evaluation with a formative focus involving document review, surveys, and interviews with students and facilitators. Results: Eighty-four percent of eligible students participated in [greater than or equal to]1 of 65 PABs. Participants said Pitt Moves provided a mental break, promoted community building, and increased their physical activity. They recommended increasing accessibility. Organizers' time was a constraint in running this program. Conclusion: Pitt Moves was feasible based on successful recruitment of participants, delivery of PABs as planned, and participant acceptability. A formal study should evaluate whether Pitt Moves can improve mood, focus, and boredom among graduate students. Organizational encouragement and audiovisuals could enhance marketing and program implementation.
