Most people telegraph their punches by winding their hands and shoulders back.
The problem with this is that the bad guy can then see the strike coming. When this happens, there’s almost no chance that you’ll land that punch. Given notice, they will be able to move out of the way, block or deflect it.
So, how do you fix this problem and HIDE your punches?!
The idea is simple: Hit from where your hands lie.
What does this mean?
Wherever your hands are, strike from there. Making the path of your hand to its target as direct as possible means you spend less energy and will hit faster. Crucially, it is almost impossible for the bad guy to detect it until it’s too late.
The ability to strike like this is a highly efficient way to attack, but it is an acquired skill that you must train to get right.
