SMOKEY POINT — Arlington residents Lynn and Bentley Marks have been expanding their businesses just south of the Arlington Airport on a semi-annual basis for the past few years, and this fall will prove no exception.

The married couple had combined skiing and snowboarding with an invention that attracted the attention of a national TV program hosted by William Shatner in 2007, and received an allowance of patent in 2008.

The Markses followed on these successes by starting a new store under a time-honored name, as Mt. Pilchuck Ski & Sport opened its doors at 5200 172nd St. NE, right next door to what was then the home of the Northwest Dance & Acro Center, in November of 2011.

In November of 2012, Lynn Marks added a drive-through coffee stand and vegetable garden to the east side of the building, and on Saturday, Sept. 28, of this year, she and Bentley will be inviting the public to an open house of XYZ Studios and Your Image Studios, two businesses that will be Mt. Pilchuck Ski & Sport’s new neighbors.

“We own the whole building now, so in addition to remodeling our own space, we’re also renting out to others.”

While Your Image Studios will offer eyelash extensions and skincare services courtesy of aesthetician Melissa Rorke, XYZ Studios will complement the athletic component of Mt. Pilchuck Ski & Sport with yoga, Zumba and Turbokick from Paige McLaren, and personal training, Pilates and TRX from Debi Terrell.

“It’s a one-stop shop for fitness,” Terrell said.

“It offers a real variety with no contracts or membership fees,” McLaren said. “You only have to pay for the services and equipment that you use. With our classes, we have plenty of choices and times available throughout the day to make it more convenient.”

“If you’re not into group instruction, we can work with you privately and one on one,” Terrell said.

Lynn Marks anticipated that 13 spin bikes would be available by the Sept. 28 open house, which is set to run from 9 a.m. to 1 p.m. that Saturday, while McLaren added that courses such as Zumba toning, the Abs and Booty Boot Camp, Sentao and “The Insanity Class” will also be on the menu.

“From 9-10 a.m. that Saturday, we’ll be offering free Zumba demonstrations,” McLaren said. “We’ll be offering free demonstrations of everything else the rest of the day. We’re even looking at offering a body-rolling demonstration.”

“We’ll have food, fun and excitement that Saturday, plus coffee,” Lynn Marks said.
