"Yeah, that's good. I actually thought we'd start with something simpler, like just a choke-hold or just a wrist-hold, but we can run with this." Damn, I was kind of hoping she'd cop a feel. No no, this isn't the time or place. Concentrate on the lesson. "A lot of the techniques I'll teach work by moving your opponent into a position where he can't get the leverage he needs to use his strength against you, and by using the limitations of his joints. I'll start with the wrist hold. Now if I try to pull my arm free by jerking it forward like this," she said as she tugged her arm against Megan's hand, "I'm working against the strength of all four fingers, but the thumb is the weak link in your grip. Now let go of my wrist for a minute and try this. Turn your arm so that your hand is palm-upward. Feel how you can twist your arm in that direction only to a certain point? Now take my wrist again. If I do this..." Emily took hold of her left hand in her right, and with the strength of both arms pulled her left arm upwards into a position that pulled Megan's hand into the palm-up position, "your arm hits the limits of its movement and I'm now pulling against just your thumb." Emily's arm easily broke loose from Megan's hold. "Now for the choke hold. Keep your head turned into the crook of your attacker's elbow as much as possible, to minimize your attacker's ability to hinder your breathing. Now most people's instinct might be to try to pull their attacker's arm away, but there's a good chance you won't have the strength to do that. Instead, take your hands and use them to clamp your opponent's arm to your chest. Now you have control of your attacker's arm, and you can shift your weight like this - " Emily slowly demonstrated the technique - "to pull your opponent off balance. Once that happens, you're in control. Depending on how big and heavy he is, you might even be able to throw him over your shoulder. Okay, want to give it a try?"
