Before you think it, I will mention it - yes, most techniques in BJJ are dangerous because it involves joint manipulation and other awkward positions. However, in this list I will talk about the moves that lack so little control that either combatant could get hurt. This means, that perhaps tapping in time won’t save you. Oh, and one more thing, this list only include legal techniques.
- Wrist Locks
We’ve all been caught by this at some point in our jiu-jitsu experience – except for maybe white belts since it’s only legal starting at blue belt. The wrist is one of the weaker joints in your body since it does not have the same support as your elbows and shoulders. Wristlocks also only really work well if they are put on very quickly. If you try to wristlock someone slowly they will more than likely escape. It can also be considered a type of surprise attack because of the speed required, which means that the damage done will be even worse if your wrist is relaxed. Wrist locks can be used from many different positions - almost any time your wrist is bent. This is another reason why it is so dangerous because it can be used on you anywhere and any time. It is a favorite of many black belts to earn an easy victory. That’s why so many people think wrist locks are considered “cheap” or “cowardly”. But the truth is, this is jiu-jitsu and if it’s legal in competition, you better be conscious of it. And if you’re a black belt, you have to be street ready, so you should definitely protect your wrists.
- Jumping Triangle
Anything “jump” related will have its problems. The jumping triangle can be done from either when both opponents are standing, or if one opponent is seated in open guard and a standing opponent jumps to catch the triangle with his legs. The reason this is dangerous is because many practitioners miss their target and the results can be quite ugly. If it fails when both opponents are standing, then the person trying the technique could easily land on his back, winding himself, or landing on his head, which can damage the spine. The bigger you are, the harder you fall. So that’s why you will always see more lightweights doing this technique. The same thing applies for this technique against a seated guard opponent. If you miss your target, you could easily kick them in the face or land on top of their head. It is definitely suggested to proceed with caution.
- Flying Armbar
This is even a step up in danger than the jumping triangle. Why? Well because for this technique you have to be on an angle where your head points more towards the ground, unlike the jumping triangle where it’s more likely that your back will hit. There are many videos out there on Youtube that show the consequences of a failed flying armbar. Many attempts lead to a practitioner knocking themselves out and having serious spine damage. So if you’re feeling light on your feet, maybe think twice before trying it out.
