Rickson Gracie thoughts on Leg Locks are probably the opposite of what a lot of people think. Recently Rickson said:
“Leg Locks are very effective, no doubts about it. It’s something really hard to defend. That’s very much it. Leg locks, knee locks, foot locks are very powerful tools to submit as armbars and chokes.
The problem is that a lot of people in the community of Jiu-jitsu don’t train too much and they only do no-gi or the guys that are coming from Sambo… I think that leg locks have to be brought to the practice to be comfortable with. Not only to execute but to defend, escape, move your hips…
Leg Locks are good practice and I like the techniques involved in leg locks.”
