Some people just naturally have that one-punch knockout power. Fighters like Mark Hunt and Dan Henderson can floor an opponent with a single well-timed punch without even putting a lot of hip power behind the strike.
Of course, the average Joe doesn’t pack that kind of dynamite in their fists. This is why you need to throw a combination of strikes in a street fight. As shown in the video, the demonstrator is a 57-year old man with some insane striking power. Even so, he emphasizes the need for punches in bunches. You need to mix it up with combinations. Don’t be afraid to throw a volley of punches, elbows, and open-palm strikes. Headbutts are fair game as well.
