The jab (the '1') is a straight punch with your lead hand, thrown from your guard and brought straight back to it. Coaching manuals use it to measure distance, disturb your opponent, set up your power punches and score, and Boxing Canada calls it the foundation of a boxer's skill. It is about speed, accuracy and a fast return, not power. The app reads your arm extension, your retraction to guard and where your rear hand sits, not punch force or an opponent.
Snap it straight
Start from your guard: lead hand between shoulder and eye height, rear fist at your chin, elbows in, chin down. Keep your lead elbow under and behind the fist so the punch drives straight instead of swinging down like a hammer.
nothing moves before the punch; no pulling back to load it.
Aim at the point of the chin and shoot the lead arm straight out along the shortest line. Snap it with a slight turn of your lead hip and shoulder toward the target. Your lead shoulder comes forward and up to cover your jaw; don't let it drop.
a quick snap from guard, the shoulder rolling in behind it.
Stay balanced over your stance. Knees stay slightly bent and the rear heel stays up. Don't lean your head forward to reach, and don't let your front leg lock straight. If the target is out of range, step instead (see Step 7).
your head stays over your feet, not out over your lead knee.
Turn the fist
Turn your forearm inward over the last part of the punch so you land palm down, striking with the knuckles and a straight wrist. Boxing Canada puts the turn in the last third of the distance.
the fist turning over just before it lands.
Keep your rear hand at your chin, thumb by your cheekbone, rear elbow tight to your ribs, the whole time the jab is out. Look down the line of the punch at your target, not over the top of your glove.
the rear glove never leaves your face.
Snap back to guard
Bring the hand back quickly along the same path it went out, all the way to your guard. Don't drop it low or swing it out to the side on the way back. You finish in the same stance you started from.
out and back on one straight line, and the return is as quick as the punch.
Add the step once the standing jab is clean. Push off your rear foot and slide your lead foot forward as the jab goes out, landing on the ball of the foot rather than the heel, then let the rear foot follow so your stance stays the same width. USA Boxing's manual says most jabs are thrown with a step; the length depends on your range.
hand and lead foot arrive together; your stance never narrows or crosses.
Feel it
Quick and relaxed: the arm snaps out and comes straight back, with the rear glove parked on your chin throughout. Your chin stays down behind your lead shoulder and your eyes stay on the target. If your shoulders are tense, the jab gets slower, so stay loose until the punch lands. The app reads your extension, retraction to guard and rear hand, not punch force or an opponent.
Fix-its
- You pull the hand back or drop it before throwing (telegraphing) Fire straight from where the hand sits in your guard. Practise in front of a mirror until nothing moves before the punch.
- Your hand comes back low or out to the side Retract along the same line the punch went out, all the way back to guard, before you do anything else.
- Your rear hand drops or its elbow flares out Keep the rear thumb on your cheekbone and the elbow on your ribs. Have a partner tap your rear glove after each jab; it should already be at your chin.
- Your chin lifts or your head leans in to reach Keep your chin down behind the raised lead shoulder and your head over your stance. If you have to lean, you are out of range: step with the jab instead.
- You land with the palm sideways or a bent wrist Turn the forearm in over the last third of the punch and land palm down on the knuckles with the wrist straight. Check it slowly on a pad first.
Drill
- Standing jabs in front of a mirror, slowly at first: guard, jab, back to the same guard. Check the rear hand at your chin and the return path every rep.
- Jab with a forward step, then with a backward step and side steps, once the standing jab is clean (the order the AIBA manual teaches it).
- Jab the bag or a partner's held glove, focusing on a quick snap and a fast return rather than pushing through.
- Partner jab/block drill: take turns throwing jabs while your partner catches them in the rear palm (gloves, mouthguard and headguard).
- Film yourself from the side at 60 fps or higher to check a straight path out and back, and from the front to check your rear hand stays at your chin. In a lab study of 15 amateur boxers the jab was the quickest of six punches to deliver, so normal-speed video can miss the return.
Safety: wrap your hands and wear gloves for bag and partner work. If you feel pain in your hand, elbow or shoulder, stop and have a coach check your technique before you continue.
How it's used
Measuring and scoring: the AIBA manual describes the straight punch as a way to judge distance, disturb your opponent's actions, prepare your main attack and score. Setting up: USA Boxing's manual adds setting your range and setting up your power punches, most simply the jab followed by the straight right (1-2). Varying it: Boxing Canada warns that a predictable jab is easy to block or slip, so once the basic jab is solid, learn to throw it at different speeds and along different paths.
