Although barre takes some positions and movements from ballet (as well as the signature ballet barre), a barre class is totally different from a dance class. You won’t typically find cardio in this workout, but rather a series of strengthening exercises targeting your core, arms, legs, and, of course, your butt. Pair that with a solid playlist, an enthusiastic instructor, and you’ve got a workout that — after you get over the soreness of your first class — becomes incredibly addictive. A few classes (and a few indulgent purchases of those super-cute barre socks) later, and you’ll be hooked.
