Share your fitness data for an Apple Watch — or cash

To entice you to stop procrastinating, your company or insurer might soon reward you for wearing a fitness device to track your steps, heart rate and more.

Vitality, a provider of disease-prevention and lifestyle programs, is initially bringing the offer to U.S. employees at three companies, along with John Hancock life-insurance customers.

Submit to biometric screenings and nutrition classes, and in some cases you can earn cash in the form of insurance discounts.

Adrian Gore, CEO and founder of Vitality parent company Discovery Group, says that for many people, the benefits from exercise might not be apparent for a few decades.

There's no proof that providing fitness trackers directly lowers health-care costs, but there's plenty of evidence that exercise leads to better health, which in turn can improve productivity and reduce absences.

Michael Staufacker, Emory's director of health management, describes the thinking as a "value of investment and not a hard-dollar return on investment as it relates to medical or pharmacy costs."

DaVita HealthCare Partners says health-care spending by its employees slowed significantly after it offered tracker-based incentives through Vitality.
