The gymnast must use both hands and work on the whole floor area whilst showing continuous flowing movement. Rob Gronkowski professes his love for math and shows off his skills in rhythmic gymnastics in a new episode of CBS' Game On! Rhythmic performances with a ball must be smooth, continuous and flowing. The ball is sometimes placed on their back while the gymnast does a skill such as a walk-over. A rhythmic gymnast, Melitina Staniouta of Belarus sits arched backwards on the floor and her arm stretched up holding a blue ball at Rio 2016.
