Synchronized swimming requires overall body strength, power, flexibility, grace, and beauty. The sport uses a swimmers ability to move quickly and gracefully while consistently interpreting the music and presenting dramatic poise. A synchronized swimmer must be able to display moves to a carefully choreographed piece of music. The competitive rules and manner of judging of synchronized swimming are similar to figure skating and gymnastics. Synchronized swimmers need strong physical endurance to perform the 3 to 4 minute routines.
