In this video, 2019 ADCC silver medalist Ffion Davies shows a brutal modified kneebar that was made famous by Amar Suloev in MMA and also recently by Zabit Magomedsharipov in the UFC.
This unorthodox leg lock/hamstring stretch is commonly known as the ‘Suloev Stretch’
According to Dr Kickass, Mike Piekarski, a Doctor of Physical Therapy, Former MMA Fighter, Brazilian Jiu Jitsu black belt. (Follow him on instagram) the mechanics of this move is similar to a kneebar, banana split and hamstring crank:
“This move is actually more of an extreme hamstring stretch than a kneebar. Traditional kneebars work by isolating the femur to create excessive hyperextension to challenge the knee ligaments. However Zabit was not able to isolate the femur based on his entry into the leglock. Without isolation he likely was not able to create sufficient torque on the knee ligaments to break them.
If it was not a kneebar than why did his opponent tap?
The hamstring group is made up of 3 muscles:
•Biceps femoris
•Semimembranosus
•Semitendinosus
These 3 muscles are maximally stretched with terminal knee extension and significant hip flexion, which mimics this position. Typical hamstring length when the knee is straight is 70-90 degrees and in this position his shin was touching his collarbone, almost 160 degrees❗️”
