Fit-breaks: incorporating physical activity breaks in introductory CS lectures

University can be a difficult, stressful time for students. This stress causes problems ranging from academic difficulties and poor performance, to serious mental and physical health issues. Studies have shown that physical activity can help reduce stress, improve academic performance and contribute to a healthier campus atmosphere physically, mentally, and emotionally. Computer science is often considered among the most difficult and stressful programs offered at academic institutions. Yet the current stereotype of computer scientists includes unhealthy lifestyle choices and de-emphasizes physical activity. This paper analyzes the effects of introducing short periods of physical activity into an introductory CS course, during the normal lecture break. Contrary to the stereotype of CS students, participation was high, and the students enjoyed these Fit-Breaks more than alternative break activities. This small injection of physical activity also had a measurable impact on the students' overall satisfaction with life, and may have had positive impacts on stress, retention, and academic performance as well as improved student perception, especially in areas that are traditionally problematic for female computer science students. Fit-Breaks are low-cost, easy to replicate, and enjoyable exercises. Instead of sitting quietly for ten minutes staring at a phone; stretching, moving, and getting a short burst of physical activity has a positive benefit for students. And the good news is: they actually enjoy it.
