I guess these are all flukes too:btw. better lift some weights.... You'll never be able to break those boards without weightlifting program.... Your vid demo is just a 'fluke.' Bulk up bro'....
Reverse Knife hand, two boards;
Reverse punch, three boards;
Spinning heel kick, two boards;
Downward punch, three boards;
Downward Knife hand strike; Eight tiles;
And all without without a weightlifting program. There goes your hypothesis.
