Move aside instructors, it's amateur hour.
Call for a front kick. Amateurs think of only the foot and putting as much power into the leg as it strikes the bag.
Think about a jab. The amateurs again only focus on their fist and flip it out. Their elbows are low, and the punch is only powered by tricep strength.
In my hard style system, power is generated by body mass and momentum. A good stable stance is only good to propel the mass of your body toward your opponent. The breath out tenses the abs so that there is transmission of power from the lower body into the upper body. Finally, the upper body tenses in order to send the power of the entire body through the respective weapon.
The weapon is the last bit of the equation, and is chosen for it's tactical advantage.
The weapon should not be thought of first.
Unless of course, it's amateur hour.
