Whats the best way to fight in UFC? What are some of the ways fighters fight with?

I'm guessing you're pretty new to the sport.

The most common arts seen in the UFC would be boxing, muay Thai, wrestling, and Brazilian jiu-jitsu.

There is no real 'best' way to fight. But in order to be successful, you'll have to have solid striking and grappling skills.

The best way to get there is just to start small in local competitions. You gotta work your way up and hope to get noticed.

In addition, it's beneficial to have a well-rounded fighting style. Train in a variety of martial arts, but without spreading yourself too thin. You can do jujitsu, muay thai, kickboxing, grappling, wrestling, boxing, etc. Good luck.
