i couldn't believe that the main girl Samantha was actually dancing

i mean she was dancing like she was a real, professional dancer and aerobics instructor and she was so flexible and could do the most amazing physical dexterity things. she was as agile and flexible as a gymnast and a ballerina. wow, she was an amazing dancer and aerobics artist.

i couldnt' believe that they got an actress who could do all those physical things. usually they have to use an actor to act and then in the dance scenes that require professional dancers they use a stunt double like in flashdance. so, wow, just wow. that was really surprising and really impressive aerobics dancing.
