This is a great workout video that really works your muscles! It focuses on lower-body strength but also adds in some arm strength and a few ab workouts. What it is, is basically warm-ups you do in your ballet class with a higher intensity. If you've never done ballet before, do not assume that it's relaxed and easy. You make it look graceful, but the moves itself are intense and challenging. But they are also doable even for someone who has never done ballet before. Just know how to point your feet!
