These dynamic new moves were going to be released in the new 6th Degree Black Manual. Great Grandmaster Al Tracy decided to add these to 2nd Degree Black Belt so more students could learn them.  The old 2nd Degree Black Belt has some complex rolling and jump kicking which are physically challenging for some students. These new moves are from what he calls the "filing cabinet". These moves illustrate "Explosive Kenpo". Students can still do the old moves but these new moves just make the fantastic Kenpo buffet even tastier.
