Jab

The lead-hand straight punch and the single most important weapon in boxing. The jab establishes range, sets up every other punch, scores points on judges' cards, and — when sharpened — finishes fights on its own (see Larry Holmes, Wladimir Klitschko, Joe Louis). A proper jab is a short, snapping extension of the lead arm, rotated knuckles-up at the moment of impact, with the lead shoulder rolling up to cover the chin and the rear hand glued to the temple as a defensive anchor. The hips and shoulder turn an inch — no more — so that the punch returns instantly. The jab is the metronome of every elite boxer's offence; everything else is a variation on it.

Key points

• ▸Lead foot, lead hand: punch and step land at the same moment.
• ▸Rotate the fist 90° (palm-down) at the last instant — not earlier, or you telegraph.
• ▸Lead shoulder up to the chin; rear hand at the temple.
• ▸Return the hand to the guard along the same line — do not drop it.
• ▸Eyes stay on the chest, not the glove you are throwing.
• ▸Exhale sharply on contact — silent breath = soft jab.
• ▸Stance stays compact: do not over-extend the lead foot.

Common mistakes

• ✗Dropping the rear hand to "load up" the jab.
• ✗Pulling the elbow out to the side before throwing (a giant tell).
• ✗Pulling the head back on retraction, opening the chin to a counter cross.
• ✗Throwing the jab off the back foot — robs it of all power.
• ✗Holding the punch fully extended ("posing") — exposed to a parry.

Drills

1. Chalk-line drill: throw 100 jabs along a taped line on the floor without crossing it.
2. Mirror jab: 3 rounds, focus on identical body alignment at retraction and at full extension.
3. Heavy-bag stick-and-move: jab + immediate step-off — left, right, or back — 60 seconds each.
4. Double-end bag: 3 rounds, jab only, counting rebounds caught cleanly.
