For most people, boxing is the most practical, and the leg method needs a lot of training to be effective. As a child below 12, his leg attack power is not obvious, his feet are fairly balanced and he can move freely. Two-handed attack is the most practical, but don't let him hit the hard sandbag, which will damage his hand, and the reaction force when hitting will seriously affect his arm and even affect his development. If he is not left-handed, practice basic movements as much as possible.

Compared with ordinary people, fighting with simple hands is like fighting with two hands. There are advantages and disadvantages!
