After the judging system changed from the 6.0 system to the ISU Judging System (IJS), dance lifts became more "athletic, dramatic and exciting". American ice dancer Charlie White stated that lifts have become "increasingly difficult", requiring teams to, like pair skaters, work with acrobats to develop their lifts. They have also become more acrobatic, despite the fact that they do not get as high as pair skating lifts because ice dance lifts cannot be supported over the man's shoulder. Dance lifts have also become more dangerous, resulting in more falls and injuries.
