1, jaw (the other party will be confused)
2, ribs (the other party will have difficulty breathing)
3, the lower abdomen (weak)
4. Bang (needless to say)
5. Knees
Even the fitness instructor can't stand it. ~~~~
It is mentioned that the fitness coach thinks that you have been to the fitness club, so it is suggested that you take a fighting class in the group class, and the coach will tell you which parts to hit each other with; It will also teach you how to punch and kick reasonably to achieve the best results.
If you can learn Thai boxing, that's the best. Among martial arts, boxing, taekwondo, karate, jujitsu, Jeet Kune Do and judo, Muay Thai is the most practical and fierce, and is good at knees and elbows.
I hope I can help you beat the fitness instructor.
