Want your badonkadonk to be a bit more shapely? Take a spot at the barre and let the burn begin. In the last year or so, Barre Evolution has been transforming flat asses into nice round bubbles with an endless supply of squats, lunges, pulses, and dips. Really. Who knew you could make your ass burn so hot by doing 10 pulses while squatting on your tiptoes? You may not leave looking like a ballerina, but you will feel the burn in your legs and arms after an hour in this fitness class.
