As far as I know, a 1hko attack is a myth invented by fighters of all backgrounds whose pursuit was a guaranteed attack that would work flawlessly. Yes you would have to train if you want to deliver a more effective attack. I would recommend shadow boxing with weights is good, if you preformed it burnout style. Meaning you start with low to high, then reverse. As far as clenching your fist goes, don't tuck your thumb within your hand. It should always be outside of your fingers. Straight punches are the most effective, because it delivers the most energy.

Aim for the jugular.
