First there was Bari Studio on Leonard, then Barre Tribeca on Warren, and then Pure Barre on Reade…. Now we have a fourth barre fitness studio in the works: Xtend Barre, opening “Winter 2017” in an undisclosed Tribeca location. (The proprietors, who live in Tribeca, are mum about it. UPDATE: It’ll be on Warren.) “Xtend Barre is Pilates and dance amplified,” says the website. “It brings in elements of dance, ballet and Pilates to create an adrenaline-fueled workout that strengthens, lengthens and chisels the body.” Founded in 2009, the brand has “62 franchised locations and 99 licensed studios on 5 continents.” There’s one New York City outpost in Brooklyn Heights; this will be the first in Manhattan. Xtend Barre also has an online program, which I’m only mentioning as an excuse to run this photo.
