In this tutorial, I give a quick tutorial on how one can condition their fingers if they don't have access to piano, like say on a trip or a long car ride...or maybe even an airplane. I used to do this during school, and when I would go on vacation so that I could "keep in shape" with my hands, I guess. I still do this during long car rides if I'm bored. Dynamic tension was derived from Charles Atlas as well as the Hung Gar style Kung Fu, Isometrics derived from Dogen's tricking tutorials.
