As health care costs continue to rise, a growing number of companies are working out programs designed to keep their employees healthy.

Thomas Chapple is the senior vice president. “It’s really important to us because medical costs are going up like crazy,” he says. “This company spends more than $ 200 million a year on medical costs for its employees around the country. The best thing we have seen as a way to control the medical cost is individual fitness.”

“We have a fitness center,” Shawn Flaherty, director of public relations for Freddie Mac., says. “We have a health benefits plan that encourages people to work out three times a week, get cholesterol （胆固醇）checks, as well as ‘do not smoke.’ If they do that, it will cost them less for the health benefits.”

Rachelle Clark works for Freddie Mac. “I feel great. You know the benefit is rewarding. I like to look good and feel healthy. I am just fortunate that I work for the company that provides some type of facility for the employees.”

While on-site fitness centers are popular, some companies pay membership fees at local gyms for employees. The companies also offer classes such as boxing, yoga and dancing. Employees see those health programs as a valuable benefit.

Tom Brook exercises five days a week. As a newspaper reporter he has a tight schedule, although Tom says it’s not that difficult for him to make time for a workout. “It is great. It is right here where we work,” says Tom. “So everybody gets a chance to use it whenever they want to. I have lost weight and never been in better shape.”

The programs may not be a magic cure for rising health costs, but they seem to have a positive impact on both employers and employees.
