Rhythmic Gymnastics
The picture shows four players performing rhythmic gymnastics in different positions. The one on the left stands on one foot, stretching his two arms horizontally, and lifting one leg as high as possible to the front to help him revolve swiftly and lightly.
The two players in the middle are standing facing each other, bending their arms near their shoulders while twisting their waists towards the left and right.
The fourth player stands on his head upside down in perfect equilibrium, without touching the floor with his arms. All these positions are close to some practiced in today's rhythmic gymnastics.
