Hyperbolic stretching is the name of a stretching program designed by Alex Larsson, who markets himself as a "flexibility and core strength expert" but his credentials can't actually be found online. His program combines several methods of stretching, including a form of PNF stretching. With this type of stretching, you use your reflexes to help you get a deeper stretch to improve flexibility. He also includes dynamic stretches (also called active stretches) and some static stretching as well.
