Everyone needed for batting"Three engines"Do you remember "Waist" "shoulder" "arm"There were three engines. In fact,"There is a fourth engine"So I would like to introduce this time.

"Fourth engine" means "return of wrist"It is.

The fourth engine that starts three engines in the order of "waist" ⇒ "shoulder" ⇒ "arm" and finally starts is "wrist return". However, this "fourth engine" is the part that is consciously moved by high school students and above who are well-formed.

Cause of door swing

The three engines produce twisting of the body, and by being aware of weight movement and axis of rotation, it becomes possible to hit a strong and fast ball.

Many players are unaware of the fact that their swing is a door swing, and they will notice it only after checking the video.

Batting like a line drawn when the door is closed. In other words, instead of activating the three engines in order and swinging the bat, Batting with the body and arm moving at the same time, with the left batter open for the right batter and the right side batter for the left batteris.

The characteristics of the players who are in the swing are:The heel of the catcher's foot rises quicklyThat point. "Raise your heels quickly"That means"Rotate your body faster"Because there is a strong awareness.


・Shoulders and arms start moving together. (The left side opens)
