I love Barre Las Vegas. I was apprehensive when I went for my first class, but it was one of the best workouts I've ever gotten. The staff is friendly and helpful, the instructor is understanding of physical limitations, and the facility is clean, well-lit and beautifully decorated. The mixed barre class is appropriate for women of all skill levels- you don't feel like a loser if you can't do everything, yet even dancers get a great workout. This class is great for stretching and toning. After the class, I felt like I achieved my goals, but I didn't feel beat up or exhausted.
My only complaints: the dressing/bathroom area is pretty small, and one wall of the classroom doesn't have a mirror, so you have to be quick to get a good spot.
