Jab, cross, lead hook, cross: how to link four punches without losing balance, where the second cross gets its power and how to exit safely.
The 1-2-3-2 is a four-punch sequence: jab, cross, lead hook, cross. It builds on the 1-2-3 that the world federation's handbook lists as an example of a three-punch sequence: lead straight to the head, rear straight to the head, lead hook to the head [1]. The fourth punch is a second cross. The handbook advises practising such sequences first standing, then with movement, and paying attention to the rotation of hips and shoulders between punches [1].
How hard is it really? Four punches in a row are a real hurdle for beginners, because after each punch you need a position from which the next one comes. Realistically you need several weeks of pad work before the four-punch sequence runs without losing balance and without dropped hands (rule of thumb).
And how fast are punches in a sequence? A single all-out punch lands at about 9.26 m/s, roughly 33 km/h; in combinations it is only about 7.5 to 8 m/s, roughly 27 to 29 km/h [3]. Hooks take measurably longer to land than the jab and cross [3]. That explains why the hook in the middle of the sequence is the moment when rhythm is created or lost.
Throw the three-punch sequence first standing, then with a step forward. The handbook teaches: punches individually standing first, then with movement, then as a combination, paying attention to hip and shoulder [1]. Milestone: ten clean 1-2-3s in a row, after each you stand in stance.
After the lead hook your weight is on the lead leg and your body is turned to the lead side [1]. For the second cross you have to reload the rear leg. A measurement on ten amateur boxers showed that the cross had the highest punch force of the six punches tested, about 1475 N, roughly 150 kg, and that rear-leg force is decisive for punch effect [4]. Another measurement found, for the cross, on average more ground force at the front than the rear foot (60.6 versus 39.4% in elite boxers) [5]. Together this means: the power comes through both legs. The conclusion that you bring your weight back towards the middle before the second cross is my inference from both descriptions, not a study statement. Milestone: you throw hook and cross directly one after the other without tipping sideways after the hook.
Four punches without speed in front of the mirror: jab, cross, hook, cross. After each punch the hand returns to the head by the shortest path [1]. The rear hand stays at the chin during the lead hook [1]. Milestone: ten slow-motion sequences, each hand returns to the head before the next one goes.
Your partner shows the targets one after another. You throw the four punches in rhythm, not at top speed. Coordinated sequences ("in synch") needed less time to land than uncoordinated ones in the study [3]. Milestone: ten sequences on the pad, at least eight clean on target.
In its tactical tips the handbook recommends starting and finishing a combination with the lead hand [1]. The 1-2-3-2 ends with the rear hand. So plan the exit: a step aside or a pivot after the last punch, hands back at the head. The handbook describes the counter attack as a response after a defence [1], so expect the opponent to answer. Milestone: after the last cross you step aside and stand in the stance.
Four punches are four opportunities to open your guard. The sequence belongs on the pad, not on a partner's head. The hand remains the most common injury site: in a British national squad there were 302 hand injuries per 1000 hours of competition [7]. Train with hand wraps and well-fitting gloves.
For sparring: boxing is a sport with head impacts. A meta-analysis of 35 studies found a clearly higher concussion risk in boxing than in other combat sports (risk ratio 0.253 versus 0.065) [8]. Sparring only under a coach's supervision, with a suitable partner, headguard and 16-ounce gloves [1]. Warning signs like nausea, confusion or dizziness after a hit require stopping at once and medical help [1].
This guide explains and motivates; it does not replace supervised training.
Count out loud, and not the punches but the return: "one – back, two – back, three – back, two – back – out." The word "back" reminds your hands to return to the head before the next punch goes. This is a practice tip without a study behind it. It turns four punches into a guided sequence in which the guard never disappears in between.
In the counting of most gyms, 1 stands for the jab (lead straight), 2 for the cross (rear straight) and 3 for the lead hook. The 1-2-3-2 means: jab, cross, hook, cross. The handbook describes the three-punch sequence 1-2-3 in words [1]. The numbers are gym convention, not a federation standard.
The cross is the punch with the highest measured force [4]. After jab, cross and hook the opponent has moved his head, and the second cross hits a new position (practice). That is the idea of the sequence, not a guarantee.
In its tactical tips the handbook advises starting and finishing combinations with the lead hand [1]. There is a reason: the lead hand lets you return to the stance. If you end with the cross as in the 1-2-3-2, you have to plan the exit deliberately.
There is no study on this. As a rule of thumb several weeks of regular pad work after the 1-2-3 works. The handbook teaches in this order: punches individually, with movement, then the combination [1].
Yes, as shadowboxing or on a standing bag. Distance and accuracy you learn on a moving target, that is pads or a partner. Start standing, as the federation teaches [1].
