In the center, a diverse mix of individuals—young and old, men and women—stand poised with jump ropes in hand, their expressions a blend of concentration and excitement. Some are adjusting their grips, while others are already bouncing lightly on their toes, warming up for the activity ahead.

A coach, wearing a whistle around their neck, claps their hands and calls out instructions, guiding the group through a series of synchronized jumps. The atmosphere is electric, filled with camaraderie and the shared joy of movement.
