Baseball, on the other hand, is a strong rotational (transverse) activity, with side-to-side (frontal) movement coming in a close second since the frontal plane precedes rotational action. To be effective in baseball, an athlete must be able to rotate well, whether throwing or hitting. This requires strong muscles around the shoulder girdle and core. In addition, baseball players need strong legs because they are used for running after balls hit into the field. And lastly, baseball players need to keep their arms loose at all times so that they can make accurate throws and hits. Overall, then, baseball is a strong sport that requires speed, power, coordination, and accuracy. It is also a very sportsmanlike game in that anyone can play it. In fact, more people play baseball than any other sport in the world. The term "baseball swing" may sound simple, but actually performing one correctly can be difficult. Correct execution of a swing involves many factors, such as the weight distribution between the left and right sides of your body, your footwork, where you focus your eyes while batting, and much more. Because of this, many people who try out for baseball teams fail because they do not know how to properly execute a swing. Even professional ballplayers have difficulty keeping their swings consistent from pitch to pitch. However, even though executing a proper swing is difficult, it is not impossible.
