Practice with a slightly heavier bat
As children reach the upper grades of elementary school, their bodies will have developed to a certain extent, so we recommend using a bat that is a little longer and heavier than the bat they normally use.
If you can swing a bat that is about 82cm/750g, you will be able to acquire a swing level that will definitely enable you to do well in junior high school baseball!
