So, this may be a potentially simple question. I understand that to get the most power out of, for example, a rear cross, one must turn the rear foot, turn at the hips and lastly at the shoulders. This, if done correctly and fluidly, will result in a stronger punch, than if you had to just punch from the shoulders.
But, where does this energy come from exactly?
I've read in other places that it comes from the ground?
I can believe this and understand what is meant, but how does a turn of one's foot bring the energy from the ground into the body?
I just can't grasp the idea, of energy just getting sucked
from the earth into somebody's foot and onwards.
Anybody care to explain?
