Metro riders, get ready to exercise to those calf muscles.

Metro says it will need to shut down escalators at its Dupont Circle and Foggy Bottom stations for a year for repairs, according to the Washington Examiner.

A Metro spokesman said time is needed because workers will have to rebuild the stairways.

The spokesman said the work is part of the transit system's $148 million, six-year repair plan for the escalators. Work on the Foggy Bottom escalators is expected to begin in January, while repairs are expected to begin soon at Dupont Circle, the Examiner reported.

A previous Metro report had warned that escalators have been breaking down more often, and consultants brought in blamed Metro's poor maintenance practices.
