The Park Slope branch of Crunch opened in the late nineties earlier this decade on the second floor of 330 Flatbush Avenue. Nearly a decade later Now, they’re expanding into the first floor and basement. A rep for the company said the new space will hold “all new cardio,” and in the basement they’re adding yoga and Pilates studios. She said construction was expected to finish in a month or so, though from the looks of it they’re going to have to, um, muscle to the finish.
