The correct way to throw punches. (in no order)

1. Don't throw unless in range or unless setting range with jab
2. Jab should be thrown sharply in a straight line from shoulder with a quick forward step or a flexed front knee and should return along the same line immediately.
3. A straight right or cross starts with a quick forward step , a pivoting of the hips so they become square to the foe, a shifting of the weight onto the front foot and a straight from the shoulder thrust so that at impact one is looking down the barrel of a gun. At impact one should rotate the wrist to maximize impact.
4. Hooks are thrown with the hips, not the arms. It is all about torque and shifting weight. They also must be SHORT with the elbow high. Uppercuts are the same on a different plane.

In short? Do what Alexis Arguello does.
