The Difference Between Jab Punch & Cross Punch

Simple, both punches are same linear straight punch type but they have different range.

Jab/Lead Hand Straight Punch used for long range punch, it has longer reach like this.

Cross/Rear Hand Punch used for short range punch, it has shorter reach but very useful when you can’t launch a Jab Punch.

Same answer with the different between Round Kick and Hook Kick, both kicks are same horizontal swing kick type but their range are different.

Hook Kick/Lead Swing Kick used for long range.

Round Kick/Rear Swing Kick used for close range.
