This is a good work out. I did it 3x with different and various exercises, for instance: for crunches i did a pilates move (10x) along with other ab workouts (I don't know their names), 10 lunges on each leg when it came to squats (along with squats), 30 high knees, 10 burpees, and so on.
here’s a workout to help you get the toned legs of a dancer. Pair this with a lot of stretching and you should notice a difference, especially in your calves, pretty quickly. For extra intensity, add dumbbells to the squats and lunges. Also, if you have a hard time balancing in the one-legged calf raises, stand near a wall or counter so you have something to rest your hand on for balance. That’s why we have barres in ballet classes!
