Competitive karate might not be a well known sport but its a fun on. Once you have started to work competitive karate you will definitely cover the two basic techniques a jab and a cross.
1. The Jab
The jab is one of the first punches you will learn because it is the most basic. A jab is a punch with your lead hand. You will punch and step with your lead foot to the head but make sure not to hit their head because that will be a foul.

2. The Reverse Punch (Cross)
The reverse punch is a highly used technique in karate because you can get a lot of momentum from it. A reverse punch is when you punch with your hand that is not forward and you can either hit your opponent in the head or not. The best thing about the reverse punch is that there are different ways to use it.
1. Body Cross
The main way someone would use a reverse punch is to the body. you can get enough power from moving in and turning your body like it is an elastic to get the power.
2. Head Cross
The head cross is just like the body cross but the target is the head. This technique is not used as much because it is a bit more awkward.
3. Timing
In karate a good timing punch is really good. It is when someone is coming in to score on you and you time them so right when they’re at a good distance you attack. The most common way of doing this is with your reverse punch, because it is the fastest.

Those are the two main punches in karate that you would learn first and to keep you ahead in your matches as well.
