Which is easier to use, military boxing, octupole boxing, palm piercing and Jeet Kune Do?

The degree of easy learning is the first, military boxing. Even the school allows students to practice during military training, which shows their ease of learning.

As for strength, it is of course octupole boxing. The name of octupole boxing is no joke. But if there is no teacher, it is still very hard to learn. Self-study can even hurt your health. After all, this is a martial art. ..

Jeet Kune Do, forget it. It all depends on Bruce Lee's fame. When Bruce Lee died, the Jeet Kune Do system was still incomplete, and few disciples became famous.

I suggest you learn martial arts, but if you don't have the perseverance, forget it. There is not a year or two when martial arts can't see its power.
