Adults who exercise regularly are happiest with their work–life balance, finds a study in the press at Human Resource Management. The authors asked 476 US working adults about their exercise behaviour. Those who worked out more than three times a week were most likely to feel positive about managing work and personal duties. Co-author Russell Clayton, who studies management at Saint Leo University in Florida, says that professionals including researchers, whose schedules can preclude long workouts, should aim to fit in brief stints each day. Lab meetings, he suggests, can involve a walk around campus — and scientists should take the stairs. “Find exercise in the margins,” he says.
