Ankle lock video
Info about "Ankle lock video"
The straight ankle lock (depending on how it is performed also known as an achilles lock) is what is usually thought of as an ankle lock. It is typically performed using the legs to isolate one of the opponent’s legs, and placing the opponent’s foot in the armpit, while holding the foot with the forearm at the lower part of the opponent’s calf, usually at the achilles tendon.
By leveraging the hips forward, the foot becomes forcefully plantar flexed, hence creating a potent joint lock on the ankle. The forearm serves as a fulcrum in the leveraging, and may cause severe pressure on the achilles tendon, especially when the bony parts of the forearm are used. Such a straight ankle lock is sometimes referred to as an “achilles lock”.
