To the song 'Meet Me Halfway'
This is a fun drill to do to a duet, if you can find a cool fast remix, as duets tend to be slow.
Everyone starts seated, at about their 60%. When there is a female vocal section, all the girls move into a standing jog with high tension while the guys stay seated. When it becomes male vocals, the guys are up, and the girls sit.
You have to find a song that is about equal, or you'll never hear the end of it!!!
Enjoy :)
