Theres a method to my madness:D
When I am looking at developing a new exercise I try to think very much outside the box. I like to read as much information on relative or not so relative issues when I am at the stage of development. I also like to exhaust every possible avenue of science within the relative areas. For instance when I was working on the Blasters there was other science at work in creating the method of stretch. I spend a great deal of time educating myself on simple machines. The A-Stretch is based on a lever and wedge. The Budled stretch is based on a screw mechanism. When I started looking at PE outside of PE I started to see some things in a different way.
The DLD Bend roots are based on this and other articles similar to this.

Genetically modified tobacco plants (Nicotiana tabacum ` Samsun’) with antisense cinnamyl alcohol dehydrogenase DNA, produce secondary xylem of a reduced tensile stiffness. These plants were grown alongside control plants. The stems of the plants were flexed or protected from flexing over a period of several weeks. The tensile moduli and second moments of areas of the different tissues inside the stems were measured and used to calculate the bending stiffness of the plants. In tobacco, the cylinder of xylem was found to be the most important tissue in determining the bending stiffness of the plants. The thickness of the xylem tissue cylinder increased when plants were subjected to flexural stimulation. This increased the bending stiffness of the stems. The response to mechanical stimulation was found to be correlated with tissue strain and the genetically modified plants were able to exactly compensate for the reduced modulus of their xylem tissue by increasing the thickness of the xylem tissue cylinder more than in control plants.
