A properly applied choke doesn't care if you are a male or a female. 120lbs or 400lbs.
If it is applied correctly, and your carotid arteries are squeezed off, (no blood / oxygen to your brain) your nervous system goes nite-nite, in a few seconds.
It is that simple.
ANYONE can be put to sleep in short order with a properly applied choke. It is not strength-dependent.
Looks like Joe showed this gal the proper technique, then allowed her to apply it to show the effectiveness. I wouldn't do that though. lol
