Do you need a fitness concierge?

To get you to stop missing workouts, SIN Workouts will do everything for you—short of lifting the actual weights.

New Yorkers have all kinds of creative ways of motivating themselves to make it to 6 a.m. fitness classes. Now, they can pay someone to do it for them.

SIN Workouts (which stands for Strength In Numbers), the brainchild of Vanessa Martin, officially launches this month, and it’s a unique fitness concierge service designed to eliminate gym-skipping excuses.

Martin, who works for a company that designs gyms for high-end residential buildings and is also a personal trainer, was inspired to create SIN after noticing that her friends relied on her for workout recommendations and accompaniment.

“I found myself creating accounts for people and signing them up for classes, and I realized, ‘this could be a really great service,’” the fit Upper West Side resident says.

She launched SIN on a small scale, and it’s been so successful that she’s now preparing to make the business her full-time job.

The company offers two packages:

In one, Martin acts as a fitness sommelier, helping you choose classes that match your personality and goals, such as sessions at Barry’s Bootcamp or Flywheel. Then, she’ll book your sessions and send you a detailed workout calendar each week. You can even get a wake-up call for scheduled classes.

In the second “elite” package, Martin lifts the glass to her clients’ lips. You get the services described above, and Martin personally accompanies you to the workouts, along with a group of up to 15 SIN members. “I offer members personalized corrections and cues that the instructor doesn’t have time for in a large class,” she says, along with the motivation that comes with being part of a group (hence, the Strength in Numbers). For an additional charge, she’ll also provide a la carte services, like post-workout laundry.

SIN memberships aren’t cheap, adding a triple-digit monthly fee onto the cost of the classes themselves (exact prices are discussed client by client), and the model seems to beg the question: Is there really a demand for this, and in this economy? Martin’s early success suggests that in some upper-crust New York circles, there just may be.

“There are some people who don’t really want to go through the mundane parts of working out,” Martin explains. “They just want the fun session when they get there.” —Lisa Elaine Held
