I’m not sure about a gym with masquerade-costumed models on its homepage, but I can’t help but be intrigued by a free 8-week yoga series.

The new fitness club Equinox (opening on Oak Lawn in August; another is opening in Preston Hollow at Hillcrest and Northwest Highway this October) promises to "wake your body gently with sun salutations and nourishing vinyasas" and will cater to you "whether this is your first time or you’re a yoga pro."

Equinox is holding its classes on the 16th floor of the W Dallas-Victory on Saturday mornings from 7-8 a.m. (ouch) starting Aug, 2 and lasting through Sept. 27. (No class on Aug. 30, which is Labor Day weekend.) All you have to do is RSVP. The flier does request, however, that "due to limited availability, your advanced and firm commitment to the event at the time of the reservation is highly valued."

If you’re a first-timer, no need to bring your yoga mat; they’re being provided by lululemon, which offers its own free yoga classes at the Galleria store on Wednesday mornings. Lululemon has also signed a lease for a Mockingbird Station location, but "they’ve hit a snag and have pushed back their store opening," says Mockingbird Station spokesman Mark Brinkerhoff. At this time, he adds, it’s "an indefinite postponement."
