Generally speaking, with regards to MMA, if a person can really mix it up in the ring they will stand a much better chance of coming out of the cage with their arm raised. A good fighter knows how to throw in strikes and moves that are unexpected and unpredictable. If you mix in different variations of punches, elbows, knees, thai kicks, teep kicks, spinning kicks, back hands, flying knees, superman punches, and the list goes on. It is far to hard to know what is coming next if your bag of tricks is over flowing.
The flying triangle is one of those moves that really agile and confident grapplers will use. It is a high risk high reward kind of move. If it goes wrong you open yourself up to getting power bombed or just knocked around. On the other hand if it works it can completely catch your opponent off guard and may even win you the match right there and then. It is also one of those moves that if you pull off and submit someone with, everyone will jump out of their seats and start running around doing the Harlem Shake.
In the video Len Sonia, the instructor, explains about the use of the knees before going into the triangle. The whole point of the knees is not just to inflict damage but it is to get your opponent’s mind thinking about the knees and not a possible submission. When you do make that initial jump up to get your legs around them you want to make sure that they do not stand to straight up and base their stance so they catch you and then slam you. You really want to pull them down as you jump up, get their weight off balance so when you wrap your legs around them you can continue to pull them downward.
Once you are on the ground you just need to follow the standard steps of sinking and locking in the triangle. Len uses a rubber guard in the video to hold his opponents head down. He grabs his own ankle and leg to hold him down while he adjusts. He mentions that he uses that under hook to shuck the arm across his body but what he does not explain is that he cuts his angle at the same time. That means he posted his back foot on his opponents hip and shifted his hips and shoulders to the side more. You have to do this to tighten the lock but as you do that the arm will be able to be move more easily.
The set up for the armbar is the same as the triangle but instead of landing on your back when you fall to the matt you shift your weight to the side so that you land on your shoulder. Landing on your shoulder cuts an angle or helps you cut an angle as you fall so that when you land you can land with his arm out straight. Also you will be able to apply more pressure if you are on your shoulder then on your back.
One thing to point out with the armbar is that as you are falling to the matt you want to slide down his arm a little bit. You need to let that under hook go because if you stay holding the under hook as you fall to the matt then they can wrap the arm under up. You want to have their arm in the lock before you hit the matt, they need to know that the armbar is happening before his knees hit the matt.
