Hapkido and Aikido are founded on roots in the Japanese martial art Daito Ryu Aiki Jujutsu. Hapkido is Korean, and Aikido is Japanese. Hapkido includes grappling and kicks, while Aikido does not and employs a more philosophical approach to self-defense.

BJJ focuses on grappling techniques similar to wrestling, whereas Muay Thai focuses on stand-up fighting using hard strikes. As a general rule, BJJ is better for self-defense and for people who are weaker and/or smaller, whereas Muay Thai is better for people who are taller with a reach advantage.

Taekwondo is not all about kicks because students learn how to strike both with their hands. But the founders believed that legs are longer and more powerful weapon than hands so taekwondo training puts a lot of emphasis on leg kicks.

As a general rule, you’re paying a high price to learn Jiu-Jitsu because certified BJJ instructors have spent many years of training to obtain BJJ black belt which is considered the most difficult black belt to get.

Amateur wrestling is a sport and Professional wrestling is entertainment. The rules differ substantially, and Pro wrestling allows strikes and acrobatics, whereas Amateur wrestling does not, and competitors are not paid.

UFC fighters can’t choose who they are going to fight next. Although fighters often use the media platform to express who they want to fight next, the UFC matchmakers are ultimately in charge of arranging bouts between fighters.
