7.15 On Leading The Final Turn
Guys, when she’s done with the spin, make a definite movement to end it, by bringing your hand (and hers) back down to waist level. There are two ways for preventing the follower from turning more:
- extend your arm (and hopefully hers),
- move her arm to a height where no turn is possible, i.e., chest height. If you lift her arm higher she can go into a turn or a neck wrap, lower and she can go into a wrap or hammer lock.
If your next step requires two hands, you should let your right hand make gentle contact with your partner’s left arm, somewhere below the elbow, as she completes her turn. That will tell her that you want the attached hand.
