Lululemon will begin selling its recently acquired Mirror home gym in 18 stores across the U.S. from this month. The cities include New York, Washington, D.C., Miami, Chicago, Minneapolis, Dallas, Los Angeles, and San Francisco.

Lululemon acquired the in-home fitness platform, which lets customers personalize their workouts by choosing from a selection of certified trainers who provide motivation and live feedback in June. Mirror was previously only available online.

Lululemon said Mirror will also roll out features including a “Face Off” option to activate Mirror’s built-in camera to allow users to compete against other members during exercise challenges.

Lululemon said in a statement, “Members will also earn points as they strive to hit and maintain their target heart rate zones. In addition, a number of interactive features will be released, such as Spotlights, which highlight Members and showcase their video feed on The Mirror once they’ve hit milestones and personal bests. Members will be able to further interact with their Mirror community using a new feature that enables people to search and follow friends, as well as send High Fives during a class to keep others motivated.”
