Freestyle aerobics is an aerobics style in which a group instructor choreographs several short dance combinations and teaches them to the class. This is usually achieved by teaching the class 1-2 movements at a time and repeating the movements until the class is able to join the whole choreography together. erobic music is used throughout the class. This is sometimes followed by a strength section which uses body weight exercises to strengthen muscles and a stretch routine to cool down and improve flexibility. Classes are usually 3060 minutes in length and may include the use of equipment such as a barbell, aerobic step, or small weights.

In freestyle aerobics, the instructor choreographs the routine and adjusts it to the needs and wants of her/his class. There is often no difference between base movements in freestyle and pre-choreographed programs.

It is practiced to improve aerobic fitness, flexibility and strength.
