2016 Best Barre Studio

Xtend Barre

It might be 6:30 a.m. on a dreary Tuesday morning, but the staff at Xtend are all smiles, laughter, and encouragement.The positivity doesn’t stop at the barre; even as you pulse, squat, and tap your way toward a quivering mass of muscle, the instructors cajole instead of scold.
