In his artcile "The Nature of Fighting" Iain wirtes
"Many of the strikes that are now punches were originally palm-heels etc. but were modified as the result of Master Itsou's changes (making the kata more suitable for children)."
Could anyone expand on this please, as I'm not sure how the change make things more suitable for children? If anything I would have thought that it makes them less suitable, as they are more likely to damage themselves punching than using heel palm.
