Volleyball develops dexterity and strength of hands, responsiveness and accuracy of the eye, as well as attentiveness. For those who play a lot of volleyball, coordination of movements is well developed.
Since you can not kick the ball with your feet, you do not need to run around the site at breakneck speed, like in football. But your legs are still training when you jump up, like on springs. The volleyball player moves are light, elegant and beautiful. And this game is not one of those that take so much power.
