Typically, the fighter bends at the waist and fires a speed jab to the midsection of his opponent in an attempt at getting the opponent to drop his guard. It is impractical to put the body weight behind this punch, so power is limited. The jab to the body can be used effectively to counter the opponents lead jab. 
Power can be added to a jab if it is thrown with a moderate step forward. The drawback to this technique is that it takes the fighter out of his boxing stance, committing him to the punch rather more than the speed jab. A "pivot jab" is the most powerful jab, one in which the weight shifts almost entirely to the lead foot, which pivots to put the mass of the body behind the punch. Jabbing from the hip, rather than from a tight guard, will add power to the jab at the expense of speed.

Holmes' jab has often been called "the best among Heavyweights", Ali's jab was famous for its speed and Liston's for its power.
