[TOMT] A music video I saw on on a tv in a dance club in Spain in 2011

This is so random and probably impossible to figure out. It was 2011, I was in Seville, Spain in a Night Club. This music video came on where there was a female gym teacher instructing all these kids how to exercise. All of the moves she was doing though we're sexy hi p thrusts, etc, to the music. Then they would cut to butterflies throughout the video. I remember liking the song as well but now I've completely forgotten it.
