This study proposes adding pre-exercise to mindfulness training to determine if it improves effects. It hypothesizes that combining exercise and mindfulness will reduce stress and absenteeism, increase job performance, and make mindfulness practice easier. Participants from a previous mindfulness study will do guided and self-guided mindfulness twice a week for 50 weeks, with 0-15 minutes of pre-exercise. Surveys will measure outcomes. Analyses will examine organizational and individual impacts, differences based on demographics and intervention level, and relationships to outside exercise. Results could help organizations implement cost-effective mindfulness programs and target specific groups.
