l was watching the olympics and the rhythmic gymnasts were not using a ball as one of the aparatusses. Does anybody know why?
Please do not guess. l want the actual answer.

There are a total of five apparatuses used in rhythmic gymnastics; ball, ribbon, hoop, clubs and rope. However, only four of those are used in the Olympic games. The FIG chooses to eliminate a different apparatus each Olympics; this Olympics, it was the ball,

There are 5 apparatus used in rhythmic gymnastics but only four are used during any given year. This year the apparatus being used at the senior level are:
- clubs
- rope
- ribbon
- hoop

The ball will be added next year and the clubs taken out of rotation.

They did use a ball l saw it maybe you missed it or something. They use 5 pieces of apparatus for the rythmic gymnastics.
