One can just use your arms to strike
But by adding footwork and hip rotation we add power.
Take the heel of palm strike.
and please dont give me that a wussy sissy punch. It has the same power as punch, looks less aggressive on video, can be done from your passive I dont want to fight stance and less chance of injuring you hand or being cut open on someone teeth and adding infections. Add i once did a seminar with military guys some army, some marines and one who was a navy seal, all that state they train open hand. So they dont bust hey hand, in the field a broken knuckle and sore finger means they cant shoot and are no useless for the mission.
If I just deliver the heel of palm with my arm only, its like getting hit with a car at say 2 km/ hour. If i add arm and hip it like getting hit with a car at 10 km/hr. But move you body in the direction of the force and its no like getting run over with a car at 60 km/hr.
Big difference.
