Is jujitsu a good martial art?

In my opinion, yes, jujitsu is very helpful when it comes to grApples, wrist locks and what not. It hardly requires any strength whatsoever because most of the attacks involve using the opponent's strength against themselves. Another good thing about jujitsu is the wrist locks, even the biggest of people have pressure points, apply these correctly and you have control of the fight. In jujitsu they not only teach you how to master pressure points but how to get out of them.
