Ask any trainer worth the spit bucket he carries what the most important punch in boxing is, he’ll tell you that it’s the jab.
While the jab isn’t glamorous and it doesn’t make highlight reels, it is the perfect punch because it sets up a fighter’s offense while, simultaneously, provides an effective defense. There are numerous approaches to throwing a jab, but the basic punch is most useful.
Start the Jab from a Proper Stance and Don't Telegraph
Assuming that a fighter has already learned proper foot placement and a relaxed but effective “on guard” stance, the jab is ready to be thrown from the lead hand. Before going any further, it is critical to keep in mind that wasted motion should be avoided. Developing “triggers” such as cocking one’s hand before throwing, feinting before every jab, lifting the lead shoulder before jabbing, or any other form of “telegraphing” must be avoided. If a fighter allows himself to develop such habits, a more experienced boxer will exploit them, with often devastating results.
For a right-handed boxer, the left jab begins from where it rests in the guard position. It moves in a straight line toward its target, with the lead foot simultaneously stepping forward and the lead shoulder driving the punch. Just before making contact, the boxer’s fist rotates clockwise so that the heel of the hand faces down. This is what’s known as the “snap” at the end of the punch. Once completed, the jab hand returns to the guard position in the same path as it was thrown. Although theories abound as to why the “snap” is necessary, it’s simple physiology, really.
How the Snap at the End of a Punch Works
Make a fist and hold your arm straight out with the thumb side of the fist pointing straight up. Now concentrate your thoughts on your biceps. Keeping your arm extended, slowly roll your fist clockwise. You should feel the release of tension as your biceps fully extend and all tension is released. That’s the snap.
Practice the Jab Effectively at Home
One can practice the jabbing motion most effectively outside the gym. Find a shelf that is chin high somewhere in the house. It could be in the kitchen, bathroom, closet, or garage. It doesn’t really matter where, as long as there is room for you to take a proper stance and move comfortably. Now take a small towel, a hand towel is perfect, and roll it up using a rubber band or tape to keep it rolled, then lay it horizontally on the near edge of the shelf.
Take your stance. Without really thinking about it, reach out and grasp the towel and bring it straight back to you. What you should gain from this exercise is that you’ve spent a lifetime grabbing objects off shelves and that you’ve always done it without wasted motion. The reason for that is purely psychological. At home, one doesn’t worry about getting punched in the mouth when he grabs a towel or a loaf of bread off the shelf. In the gym, even in front of an innocuous heavy bag, psychological tension causes the fighter to telegraph his jab, as well as other punches.
Continue to practice this “shelf technique" for a few minutes every day. Before long you will have a jab that’s more relaxed, cleaner, and more difficult to counter in the ring.
