Fighting. Always fighting. First, they always do all that Aikido bullshit against multiple opponents and it works because their opponents are fighting completely ridiculously. Second, most people don’t know how to do anything but stick their chin up in the air and throw windmill punches. Even in a movie she’s it’s just two guys in a bar throwing down, they both are somehow at least golden gloves boxers. Third, they always fight forever and take way too much damage. Unless they’re professional fighters, two people off the street are going to last about 30 seconds to a minute before they gas completely. And they always take ridiculous amounts of damage in movies. Like the type of damage that would kill someone.
