Daniel debuts his video on how to punch with real power. Having first hand experience on the receiving end of his strikes, I can attest that his techniques work. Even smaller people who use his street methods of punching are no fun to fight with. I equate to being hit by a polar bear.
In this video Daniel shows how to punch via the two knuckle or three knuckle landing. He explains how to punch bare-knuckle using the three knuckle landing and why. He also covers the difference between each type of fist position.
Each strike has it's advantages, that's why I don't tell anyone not to use the two knuckle landing, because it does work. Just keep an open mind and try using the three knuckle landing or as Jack Dempsey called it "The Power Line".
Daniel is a walking encyclopedia on street fighting with the bona fides to back it up. It's a long video, but well worth the time as I guarantee you will learn something new.
And see if it doesn't increase your punching power for boxing or for street-fighting.
