Created by professional ballerina and celebrity trainer Mary Helen Bowers (she worked with Natalie Portman for her role in Black Swan), the Ballet Beautiful website offers live, interactive online classes and pre-recorded streaming videos. All ballet-inspired, both the videos and class options include targeted toning exercises, stretches, and high- and low-impact cardio workouts designed to build sleek, sexy muscles and beautiful ballerina posture.
The website offers monthly subscriptions to the continually expanding workout video library, or you can "attend" a live, interactive class with Bowers herself.
Cost: $35/class or $40/month
