Neckbreaker 2 DVD Set with Erik Paulson
Erik displays a dizzying array of cranks, face locks, chokes, neck crank set-ups, and submissions that can be set-up by neck cranks (e.g., arm bars) from the ground and standing. He included variations for competition but for the street as well.
As Erik says, "these techniques aren't nice" and are designed to make even the toughest opponents concede.
Bonus material includes in-depth stretching and a large portion of Erik's personal "Ultimate Killer Neck Routine". Also, see Erik neck crank his way through five live opponents back-to-back during an actual training session at CSW headquarters in Fullerton, California!
